Oxygen (2021)

Oxygen is an exercise in sustained psychological tension that leverages claustrophobia as its dramatic engine. Director Alexandre Aja constructs a survival thriller where the true enemy is not technology nor outer space, but time itself, which is running out. Mélanie Laurent effectively carries the narrative weight alone, and the script intelligently manages the progressive revelation of information. The film poses legitimate questions about identity and memory within a science fiction context without descending into vague philosophies: everything serves the suspense.

For parents, the warning is clear: the tension is constant and the anguish palpable. There is no graphic violence nor visceral horror, but the confinement and despair can prove overwhelming for young or sensitive viewers. The language is moderate, limited to expressions of panic understandable given the situation. There is no sexual content nor ideological agenda. It is competent genre cinema that demands emotional maturity from the viewer, but without morally problematic elements. Appropriate for older teenagers and adults who appreciate a well-executed psychological thriller.
