OUT NOW, PG-13 ★★★✩✩
A hell of a surfing trip! Blake Lively is a medical school dropout trapped in the ocean by a killer shark in a tense thriller that’s often goofy (although it’s smarter than Sharknado) but occasionally gripping (à la Open Water). Blake talks to herself and uses her ingenuity in what amounts to a B-movie take on survival stories like Gravity
and The Revenant.
