Common Sense Note

Parents need to know that there's a fair amount of salty language in this ocean thriller. The camera exposes bare breasts in a medical-emergency context. Violent acts include death by drowning, hand-to-hand combat, and a threat of nuclear annihilation. Young viewers with fears of the water and/or claustrophobia might be uncomfortable with vivid portrayals of drowning and submersible environments. A scene -- not faked -- in which a domesticated rat is immersed in breathable liquid is a real don't-try-this-with-the-family-pet-at-home moment. The US military doesn't come off looking particularly good.

Sexual Content

Quick glimpse of bare breasts as a female character in cardiac arrest is defibrillated.

Violence

Blood shed in hand-to-hand combat and near-strangulation. Freshly-drowned bodies shown. A knife and a gun brandished. A montage of real-life atrocity footage from Vietnam, the Holocaust, and other infamies. A psycho character slashes his arm in a masochistic "cutting" ritual.

Language

"Damn," "hell," "dick," "SOB," and "s--t," all several time; "goddamn"/"oh my God"; the heroine referred to as a "bitch" more than once.

Social Behavior

The U.S. military (in particular, an all-white group of overconfident Navy SEALS) are more or less the villains here, arrogant and paranoid and fixated on weaponry and Cold-War destruction. The filmmakers' sympathies are with the (ethnically and sexually mixed) working-class oil-rig crew, shown as more sensible and concerned for each other's safety and well-being. The main characters are a feuding couple in the process of divorce, with lots of marital sniping woven into the adventure; the wife in particular is accused of being more interested in career advancement.

Consumerism

Somehow a Coca-Cola machine found its way on board the base.
