I don’t particularly like underwater films. That context belongs in this review because it affects the experience of watching The Abyss in ways that are honest to acknowledge. The specific qualities that make underwater cinema distinctive — the claustrophobia, the pressure, the visual murkiness, the particular kind of dread that comes from being in an environment that will kill you if your equipment fails — are qualities I find more oppressive than immersive. So my rating of 7 is probably generous relative to what an enthusiast for the genre might give it, and comes with the caveat that the genre itself is working against my natural tolerance rather than with it.
With that said: The Abyss is two-thirds of a great film followed by an ending that doesn’t honor what preceded it. Cameron built something tense and claustrophobic in those first two acts, with performances that go beyond what the genre usually asks for. Then the aliens arrive in force and the film loses its nerve.
What Cameron Built
The production achievement of The Abyss is extraordinary even by Cameron’s standards. The underwater photography required actors and crew to work in conditions of genuine physical hardship — extended time in water tanks, breath-holding sequences, the specific performance demands of an environment that doesn’t allow for comfort or easy communication. The results are visible on screen in ways that CGI-heavy productions can’t replicate. The claustrophobia is real because the environment generating it is real.
The Deepcore rig is a superbly designed setting — confined, functional, full of the specific texture of working machinery that Cameron consistently brings to his industrial environments. The Nostromo in Alien had this quality. The future Los Angeles of Terminator had it. Deepcore has it too: a place that feels used rather than designed, where the details communicate a world that exists beyond the frame rather than stopping at it.
The political subplot — Coffey’s NLD-induced paranoia, his increasingly dangerous interpretation of every event as Soviet aggression, his determination to arm the warhead — is the film’s most interesting human antagonism because it’s grounded in something real. Michael Biehn plays the deterioration with genuine precision: a man’s whose psychology is breaking down in a particular direction, becoming more certain and more dangerous in proportion to how wrong he’s becoming. The NLD is established early as a known risk of extreme pressure environments. When Coffey starts showing its symptoms, the film doesn’t label them — it just shows the behavior and trusts the audience to connect it to what was established.
Coffey is a model for how to write a human antagonist whose danger comes from a comprehensible psychological process rather than from villainy. His paranoia follows logically from his condition, his environment, and his training. He’s not wrong that there are threats — he’s catastrophically wrong about what they are and who they come from. Writing antagonists whose behavior has a logic you can trace produces characters the audience can understand even while opposing them. Antagonists who are simply obstacles produce less interesting opposition than antagonists who are making decisions that make sense from inside their own psychology.
Ed Harris and Mary Elizabeth Mastrantonio
The performances are the film’s strongest element. Ed Harris as Bud Brigman brings a man’s who leads through competence rather than authority — someone who knows the rig and the people on it well enough that authority is a formality rather than a necessity. His relationship with Lindsey is the emotional core of the film, and Harris plays the specific texture of a marriage that ended because of work but never stopped mattering in ways that both parties would rather not acknowledge.
Mary Elizabeth Mastrantonio’s Lindsey is one of the better female characters in Cameron’s filmography precisely because she’s difficult in ways the film treats as character rather than flaw. She’s demanding, impatient, brilliant, and not particularly interested in managing how other people experience those qualities. When she makes mistakes — and she does — they’re mistakes that come from who she is rather than from narrative convenience. The revival scene, where Bud spends several agonizing minutes performing CPR on her after she drowns, is the film’s emotional peak because both performers are fully present in a specific situation rather than playing toward an emotion. Harris’s desperation and exhaustion are physical. Mastrantonio’s confusion and grief when she wakes are specific rather than generic. The scene works because Cameron earned it through the sustained relationship development that precedes it.
The revival scene demonstrates how to make an emotional peak land: spend the entire preceding film building the specific relationship whose stakes the scene depends on. The scene itself is not the work. The forty minutes of specific, detailed relationship development before it is the work. By the time Bud is performing CPR on Lindsey, the audience has accumulated enough investment in their specific dynamic that the scene’s emotional weight is proportional to the investment. Emotional peaks in stories are collection moments — they collect the investment built across all the preceding scenes. If the investment isn’t there, the collection is empty.
The Ending Problem
The film earns its first two acts completely. Then the aliens arrive in force and Cameron trades what he built for something easier.
The ending Cameron delivers — the NTIs showing Bud humanity’s nuclear arsenal, threatening to destroy the surface world, then relenting when Bud’s message about human love reaches the Chairman — is visually spectacular and thematically dishonest. The film spent two acts building a specific argument: that human beings under extreme pressure reveal both their worst impulses and their capacity to transcend them, and that the transcendence is earned through choices rather than through generic goodness. Coffey represents the worst. Bud and Lindsey’s reconciliation represents the best. Both are developed through behavior over a sustained period.
The alien intervention doesn’t emerge from any of that. It arrives from outside the story and resolves tensions the story should have resolved from within. The NTIs decide not to destroy humanity because of Bud’s love for Lindsey — but that decision is made by beings who are not part of the human drama the film built. It’s a resolution imposed from outside rather than grown from within, and the audience feels the difference.
The director’s cut is better than the theatrical version — it extends the alien sequence enough to give it some weight and context. Neither version fixes the fundamental problem. The 7 is for what the film is for the first ninety minutes. The ending costs it the rest.
The Abyss failure is a clean example of a story that builds one argument and ends with a different one imported from outside. The film’s first two acts argue that human beings contain both Coffey and Bud — destruction and love in tension, with the outcome determined by choices in specific circumstances. The ending argues that love wins because the aliens said so. Your ending must emerge from the same logic as your preceding story. External resolution — a deus ex machina, an outside force that settles what your characters couldn’t settle themselves — is almost always felt as a betrayal even when audiences can’t name exactly what went wrong.
The Underwater Problem
Speaking as someone who doesn’t love underwater films: The Abyss demonstrates both why the setting works and why it creates specific challenges for audience engagement that other confined environments don’t.
The claustrophobia is real and effective. The specific dread of equipment failure in an environment that can’t support human life is different from the dread generated by, say, a haunted house or a spaceship — it’s more physical, more immediate, more tied to the specific fact of biological vulnerability. Cameron uses this well in the middle act, where the threat of oxygen depletion and the physical difficulty of everything the characters do generates sustained low-level tension that doesn’t require action sequences to maintain.
But the visual murkiness that’s inherent to underwater cinematography also works against the film’s emotional moments. The clarity that emotional performance requires — the ability to read faces, to track subtle expressions, to feel the full force of what’s happening — is compromised by an environment that literally obscures. The film compensates with close-ups and careful lighting, but the challenge is real and partially unavoidable.
The Verdict
The Abyss earns its 7 as a film with two excellent acts, one strong performance, one great performance, and an ending that trades what it built for something easier and more comfortable. The production achievement is genuine. The performances from Harris and Mastrantonio are among the better work in either actor’s career. The setting generates real tension even for a viewer who doesn’t love underwater cinema.
The ending is a real failure, not a small one. It doesn’t just disappoint — it retroactively changes the question the film was asking from “what do human beings reveal under this specific kind of pressure” to “will the aliens decide humanity is worth saving.” Those are different questions with different stakes and different emotional investments. Cameron built one film and ended with the other, which is why the 7 is the ceiling rather than the floor.
FAQ
Theatrical cut or director’s cut?
Director’s cut, if you’re going to watch it. The theatrical cut removes the alien confrontation sequence that explains the NTIs’ behavior, which makes the ending feel even more arbitrary than it already does. The director’s cut doesn’t fix the fundamental problem but it makes the resolution more coherent within its own terms.
Is it worth watching if you don’t like underwater movies?
The first two acts are worth watching regardless. The setting is oppressive in the way that’s unavoidable in underwater cinema, but Cameron does enough with the human drama to compensate. The revival scene alone justifies the investment. The ending will frustrate you, but it will frustrate most viewers regardless of their feelings about the setting.
What makes Coffey work as an antagonist?
His logic is comprehensible. NLD under extreme pressure is a documented phenomenon. Coffey is following military training that makes sense in most situations and produces catastrophically wrong conclusions in this one. He’s not irrational — he’s applying rational thinking to a situation where his perceptions have been corrupted by his condition. That specific kind of antagonist, whose decisions follow from a logic you can trace even while recognizing it as wrong, is more interesting and more frightening than generic villainy.
How does it compare to Cameron’s other films?
It sits below T2 and Aliens because the ending fails in ways those films’ endings don’t. The production achievement matches or exceeds both. The performances are among Cameron’s best work as a director of actors. The structural failure is more significant here than in his other films because The Abyss builds something more intimate than his larger spectacles, and the ending is more jarringly out of register with what preceded it.
