The Last Breath

Sharks, while undeniably lethal, are also, studies have shown, kind of dumb. And “The Last Breath” is a cheesy new thriller that is even dumber than a real shark. Not that it features any real sharks — the predatory creatures here are CGI, and hilariously enough, they move through the water faster than the “rage virus” zombies of “28 Days Later” roam over land.

They don’t show up until about halfway through the Joachim Heder-directed movie, which begins during World War II, and the shelling of a ship that results in a wreck that’s apparently legendary in the present day. That’s according to old salt Levi (Julian Sands) whose rickety boat is playing host to a group of self-proclaimed “certified divers” who are also kind of pushy, to say the least. At least the males in the group are. There’s peroxided wannabe Alpha Brett (Alexander Arnold) and entitled stoner Logan (Arlo Carter), who wonders aloud at the dock whether a local ten-year-old would sell him weed. Rarely have two characters been presented so immediately as those whose deaths you will actively root for. But I’ll refrain from spoilers.
