...t’s entertaining to revisit the classic tropes of submarine movies: claustrophobia, tense silence, sweating faces, cat-and-mouse strategy – all ingeniously played out between people who are supposed to be on the same team.

Vi bjuds på klaustrofobisk terror, den djupaste av militärisk byråkrati och lite kärlek i denna kompetenta undervattensthriller.

...a surprisingly engaging exercise in genre filmmaking.

There's much to recommend in this film, including taut pacing, a thriller premise, and an appealing lead character with a powerful set of ears.
