Kristen Stewart stars in a scene from the movie "Underwater." The Catholic News Service classification is A-III -- adults. (CNS/Fox)

Tedious survival slog follows an electrical engineer (Kristen Stewart) and some of her colleagues (led by Vincent Cassel) as they escape the severely damaged underwater drilling facility where they’ve been living and working and head for the shelter of a similar structure nearby. But the mysterious creatures that inflicted the destruction are not inclined to let them pass in peace.

Like the ocean depths in which it’s set, director William Eubank’s monster movie is dim and murky as it alternates between the boredom of spending time in the company of one-dimensional characters and brief outbursts of nasty mayhem.

Brief but intense scenes of violence with much gore, a few uses of profanity and a couple of milder oaths, at least one rough and several crude terms, a bit of crass talk. The Catholic News Service classification is A-III — adults. The Motion Picture Association rating is PG-13 — parents strongly cautioned. Some material may be inappropriate for children under 13.
