An essay on Avengers: Infinity War, Avengers: Endgame, and the central structural failure that defined the MCU’s transition from peak franchise to declining property. Linked from every Phase One through Phase Four review and from the MCU overview.
The Scale Of The Event
In Avengers: Infinity War, the character Thanos snaps his fingers while wearing the Infinity Gauntlet and exterminates half of all living things in the universe. The event is depicted on Earth as the disintegration of approximately three and a half billion people. The depiction is also explicit that the snap affects all life, not just humans. Half of all animals die. Half of all plants die. Half of all microbes die. Half of every biome on Earth and on every other inhabited world in the universe vanishes simultaneously.
The closest historical reference for an event of this magnitude is the Cretaceous-Paleogene extinction event approximately sixty-six million years ago, in which a combination of asteroid impact and subsequent climate disruption killed approximately seventy-five percent of all species on Earth. The dinosaur extinction is the standard scientific reference point for what happens to a planet when a significant portion of its biosphere dies in a short timeframe. The consequences of that event included global ecosystem collapse, the extinction of multiple major animal groups, the rearrangement of food chains across millions of years of recovery, and the transformation of Earth’s climate and chemistry.
The MCU’s Snap is described as affecting fifty percent of all life. The reality of a fifty percent simultaneous biosphere loss would be civilizationally catastrophic at a scale the MCU does not depict and does not attempt to depict. The films treat the Snap as a dramatic plot point with emotional consequences for specific characters. The actual event the films describe is closer to a planetary near-extinction. The gap between what the script describes and what the script depicts is the central structural failure of the Infinity Saga’s conclusion.
What The Snap Would Actually Have Looked Like
Consider the immediate consequences of half of all humans disintegrating simultaneously on Earth.
Aviation: at any given moment, between five hundred thousand and one million people are airborne globally on commercial flights, military aircraft, private planes, and helicopters. Half of these people vanish. Half of all pilots vanish. Half of all air traffic controllers vanish. The result is not just thousands of crashes occurring simultaneously across the globe. The result is the immediate destruction of all functional aviation as a system, with secondary consequences including ground impact damage, fires, and infrastructure destruction across the world’s major airports and flight corridors. Spider-Man: Far From Home glanced at this concept with the casual line about planes falling out of the sky but did not pursue it.
Surface transportation: highways are full of cars at any given moment. Half of all drivers vanish from moving vehicles. Trains operating at high speed lose half their crews. Ships at sea lose half their personnel including ships transporting hazardous materials. The immediate consequence is mass collateral death among the surviving half of humanity from accidents that occur simultaneously across the entire globe in the seconds and minutes following the Snap.
Medical care: every surgery in progress at the moment of the Snap loses either the patient or critical surgical staff. Every operating room in every hospital across the planet becomes a death scene. Patients in intensive care without their attending nurses die. Patients in dialysis die. Patients on life support whose machines lose half their monitoring staff die. The medical infrastructure of the planet collapses in the same instant the Snap occurs and the collateral death toll from medical failure alone is potentially in the tens or hundreds of millions.
Critical infrastructure: nuclear power plants lose half their operators. Chemical plants processing dangerous materials lose half their safety personnel. Water treatment facilities lose half their staff. Electrical grids lose half their maintenance and control personnel. The immediate aftermath of the Snap would include nuclear accidents at facilities operating without sufficient staffing, chemical disasters at production facilities, and cascading failures across the global power grid. The MCU shows none of this.
The biosphere: the Snap kills half of all non-human life simultaneously. Half of all pollinators vanish. Half of all soil microorganisms vanish. Half of all decomposer organisms vanish. Half of all phytoplankton in the oceans vanish, with immediate consequences for atmospheric oxygen production. Half of all gut bacteria in humans and animals vanish, with potentially fatal digestive consequences for surviving organisms. The ecological cascade from a fifty percent biosphere loss would dwarf the human civilizational impact and would render most of the surviving Earth uninhabitable within months.
None of this appears in the MCU’s depiction of the Snap. The films show specific characters disintegrating into ash and focus on the emotional impact for the surviving named protagonists. The actual event the films describe would have ended civilization within weeks. The five-year period between Infinity War and Endgame would have been the period of complete civilizational collapse rather than the period of slightly diminished functioning the films depict.
Why Infinity War Is Too Complicated
Infinity War attempts to coordinate the activities of approximately forty named characters across multiple plot threads on multiple planets converging toward a single climactic event. The Russo brothers’ direction handles the logistical challenge of giving each character meaningful screen time better than most filmmakers could have. The aggregate result is still structurally overloaded.
The film splits into approximately five major narrative threads: the Vision and Wanda subplot at the start, the Thor space adventure with Rocket and Groot, the Earth-based Avengers in Wakanda with the Vision rescue mission, the Guardians of the Galaxy plus Iron Man plus Spider-Man plus Doctor Strange thread on Titan, and the Thanos pursuit thread that ties through all of them. Each thread has its own plot logic, its own emotional stakes, its own supporting characters, and its own climactic beat. The film’s two-hour-thirty-minute runtime is insufficient to give any single thread the attention it would have received as a standalone film.
The audience is asked to track twenty-plus character arcs simultaneously. The audience is asked to remember plot points and character histories from a decade of previous films. The audience is asked to invest emotionally in losses that occur during the climactic Snap without having had time to invest sufficiently in any of the characters being lost. The Snap as filmed is emotionally affecting because the audience brought emotional investment in from previous films. The Snap as filmed would not be emotionally affecting if Infinity War were the only film these characters had appeared in.
The complexity is the film’s primary craft achievement and its primary structural problem. The Russos managed to deliver a coherent narrative across the complexity. The narrative they delivered is also less than it should have been because the complexity prevented sustained investment in any single element. A simpler version of Infinity War with fewer threads and tighter focus would have produced a more dramatically satisfying film. The version the Russos delivered is impressive logistically and inferior dramatically to what tighter construction could have achieved.
Why Endgame Is Contrived
Endgame is the most contrived major blockbuster film of the past decade. The contrivance is not accidental. The film is essentially a fan-service delivery system structured around the time-travel premise that allows the surviving Avengers to revisit every previous major MCU film. The structure exists because Marvel Studios determined that the climactic film of the Infinity Saga needed to provide closure for every major character thread the franchise had built across eleven years.
The time-travel rules the film establishes are coherent enough to function as plot machinery. The rules are also clearly retrofitted around the destinations the film wanted to visit. Tony Stark and Steve Rogers return to the 2012 Battle of New York because the film wants to revisit that location with current technology and current cast. Thor and Rocket return to 2013 Asgard because the film wants to revisit Asgard with current production resources and recent character development. The destinations are not selected because the plot requires them. The destinations are selected because the fan service requires them and the time-travel mechanism is reverse-engineered to justify the visits.
The climactic battle is structured as a fan-service portal sequence in which essentially every surviving character from every previous MCU film appears simultaneously on the Wakanda battlefield. The “Avengers, assemble” moment that Steve Rogers delivers is the most quoted moment in MCU history and is also the most pure expression of fan service in the franchise. The audience receives the emotional payoff because the audience has been waiting for the payoff for over a decade. The structural justification for the moment is essentially: the audience wanted this, therefore the film delivers it. The deeper question of whether the moment is earned by what came before is set aside in favor of the visceral satisfaction of the delivery.
The Tony Stark sacrifice that resolves the film is the most dramatically affecting beat in the runtime and is also the most directly contrived. Stark’s character arc across the Infinity Saga had been about responsibility, fatherhood, and the cost of his earlier irresponsibility. The arc culminates in a moment in which he sacrifices himself to save the universe while wearing a gauntlet that contains the Infinity Stones. The composition of the moment is intentional. The moment is meant to be the perfect culmination of his arc. The construction of the moment is also visible if the viewer looks past the emotional affect. The film engineers the situation specifically to allow Stark to make the sacrifice. The sacrifice is the destination the film is heading toward from the opening scene. The “I am Iron Man” line that closes the moment is constructed by the writing team to mirror the line that opened the franchise eleven years earlier. The mirror is intentional. The mirror is also a writer’s construction rather than a character’s choice.
Contrivance is not always a failure. Contrivance can produce effective drama if the construction is invisible. Endgame’s contrivance is sometimes invisible (the Tony Stark sacrifice lands for most viewers despite the construction) and sometimes visible (the time-travel destinations feel chosen for nostalgia rather than for plot necessity). The aggregate effect is a film that succeeded commercially on a scale no film had succeeded at before and that has aged less well than its initial reception suggested. The contrivance becomes more visible with each rewatch because the emotional momentum of the original viewing experience wears off and the construction underneath becomes the dominant element.
The Five-Year Gap And The Second Catastrophe
Endgame establishes that five years pass between the Snap and the Avengers’ time-travel solution. The film handles this period through brief montage and dialogue rather than through sustained depiction. We see Steve Rogers running a support group for grieving survivors. We see Tony Stark living as a father with Pepper Potts. We see Hawkeye operating as a vigilante killing criminals across the globe. We see Captain Marvel attending to space-scale problems. The five-year period is essentially treated as a downtime montage between the Snap and the Snap’s reversal.
What the five-year period would actually have looked like is something the MCU systematically refuses to depict. Half the world’s population is gone. Half the world’s economy has collapsed. Half the world’s food production has stopped. Half the world’s infrastructure has degraded. The surviving humans are dealing with mass trauma, mass economic dislocation, mass infrastructure decay, and the gradual realization that their civilization may not be recoverable. The MCU treats this as the backdrop for the Avengers’ emotional regrouping and shows essentially nothing of the global situation the script has implied.
The reversal at the end of Endgame creates a second catastrophe that the MCU systematically refuses to engage with. Three and a half billion people return to Earth simultaneously after a five-year absence. Their homes are occupied by surviving family members, by people who moved into vacant property, or have been destroyed entirely. Their jobs are filled by surviving workers. Their families have moved on, remarried, had new children, mourned them, and built new lives. Their bank accounts may have been closed or distributed to surviving heirs. Their identities legally may have been declared deceased.
The Falcon and the Winter Soldier series in 2021 attempted to engage with this aftermath through the Flag-Smashers subplot about displaced returnees. The series was the only MCU project to take the second catastrophe seriously. The reception was mixed because the series tried to address something the films had been refusing to address and could not reconstruct the missing context across one season of television. Most other MCU projects have treated the Blip as either background detail or comedic premise. Spider-Man: Far From Home includes a sequence in which “blipped” school band members reappear in the middle of a basketball game. The sequence is played for laughs. The depiction is the most explicit example of the MCU treating mass return as comedy rather than as the second catastrophe it would actually be.
The dinosaur-extinction comparison applies to both events. The Snap itself was a planetary near-extinction event. The Blip is a second planetary disruption event of comparable scale. The civilization that survived the first event is destabilized by the second event in different ways. Population doubles instantly with no corresponding doubling of resources, infrastructure, housing, food production, or governmental capacity. Refugee crises at unprecedented scale follow. Conflict over reclaimed property follows. Identity disputes over the legal status of returnees follow. Mass psychological trauma at the individual and collective levels follows. The MCU shows essentially none of this.
The Comedy Problem
The most damning element of the MCU’s handling of the Snap and the Blip is the consistent decision to treat both events as comedic material. Spider-Man: Far From Home’s basketball-court reappearance gag established the tone. Subsequent films and series have referenced the Blip as background detail without engaging with its weight. Shang-Chi includes a “Thanos Was Right” coffee mug as visual gag. Hawkeye references a “post-Blip anxiety hotline” as joke. The MCU is treating its own central catastrophic event as material for incidental humor across multiple subsequent projects.
The comedy framing extends the Ragnarok problem identified in the Thor: Ragnarok review. The franchise lost the capacity to take its own mythology seriously. The Snap should have been the franchise’s most weighty single event. Subsequent treatment has reduced it to background atmosphere and incidental jokes. The audience cannot maintain emotional investment in events that the franchise itself does not take seriously. The decorative-comedy approach that began with Ragnarok metastasized through the Infinity Saga conclusion into the Phase Four collapse. The Blip’s treatment as comedy is one of the clearest pieces of evidence for this trajectory.
What The MCU Got Right About The Stones
The Infinity Stones as a unifying concept across Phases One through Three worked. The Stones provided the franchise with a structural spine that gave individual films purpose beyond their own contained narratives. Each Stone had specific properties, specific historical context, and specific narrative function. The Tesseract that appeared in Captain America: The First Avenger turned out to be the Space Stone that drove the plot of multiple subsequent films. The Aether in Thor: The Dark World turned out to be the Reality Stone. The Mind Stone embedded in Vision’s forehead became the central object of the Avengers: Age of Ultron plot. The chain of connections across the films gave the franchise its sense of accumulating consequence.
The Stones also functioned as a credible cosmic-scale threat. The premise that there are six objects of universe-shaping power and that a sufficiently determined villain could collect them all gave the franchise a clear endgame trajectory. The audience could track the progression toward Thanos’s eventual acquisition of all six Stones across multiple films. The narrative spine worked.
The handling of the Stones during the Snap and the post-Snap recovery is where the franchise lost its grip on what it had built. Thanos destroys the Stones immediately after using them, eliminating the central narrative device the franchise had been building toward for over a decade. Endgame’s time-travel solution involves retrieving the Stones from different points in the past, which functionally retains the Stones as plot devices while having them destroyed in the main timeline. The complexity of the solution undermines the structural elegance of the Stones as concept. By the end of Endgame, the Stones no longer exist in the MCU’s main timeline. The structural spine that had unified eleven years of filmmaking is removed from future stories.
What replaces the Stones as the franchise’s structural spine in Phase Four is the multiverse, which is the subject of the companion essay linked below. The multiverse is not a structural spine because the multiverse has no edges. The Stones were finite (six objects, specific powers, specific locations). The multiverse is infinite (uncountable parallel realities, uncountable character variants, uncountable possible plot mechanics). The transition from finite stakes to infinite stakes is the transition from a franchise with consequences to a franchise without them. The Snap and the Blip were the last sustained engagement the MCU had with finite stakes. Everything after has operated in the multiverse register that the companion essay addresses.
The Catastrophe The MCU Refused To Show
The Marvel Cinematic Universe spent eleven years building toward an event it then refused to depict. The Snap is described as a planetary near-extinction. The Snap is shown as the disintegration of specific named characters with selective ash effects that do not depict the actual mass-casualty event the script describes. The five-year period of catastrophic civilizational decline is depicted as a downtime montage. The Blip’s restoration of three and a half billion missing people creates a second catastrophe that subsequent films have treated as comedy. The franchise’s central event has been systematically deflated across every subsequent project rather than being honored as the planetary catastrophe it actually represented.
The decision to refuse depiction is the franchise’s clearest sign of its post-Endgame collapse. A franchise that cannot honor its own central event with the seriousness the event requires cannot maintain audience investment in future events. Captain Marvel’s failure, the Phase Four collapse, and the ongoing Phase Five recovery problems are all downstream consequences of the Infinity Saga’s refusal to depict what it had described. The audience that watched Thanos’s victory in Infinity War expected something proportionate to the scale of the loss. The audience received a five-year time skip, a time-travel solution, a fan-service portal sequence, and a contrived sacrifice that resolved the narrative without engaging with the consequences of the event it was resolving.
The MCU’s actual achievement in Infinity War and Endgame is more limited than the commercial performance suggested. The films delivered the immediate emotional satisfaction the franchise had spent eleven years setting up. The films also avoided the harder work of depicting what their own premise required. The franchise has been paying for this avoidance ever since. The Snap and the Blip should have been the events around which the next decade of MCU storytelling organized itself. Instead they became background detail and occasional comic relief. The franchise that could not honor its own central catastrophe could not sustain audience trust in subsequent stories. The decline that followed is structurally connected to the choices made in 2018 and 2019.
