A diverting night at the movies for fans of the killer shark genre

While surfing alone off a secluded beach, Blake Lively is attacked by a computer-generated Great White. She makes it to a rock, then a buoy, but she’s still a maddening 100 meters from safety. Lively gets to show off her range in this beauty-vs.-beastie bit of chum (not to mention a bit of T&A).

There’s not a lot new in this busy, athletic millennial B-movie from Jaume Collet-Serra (Run All Night, Orphan, House of Wax), but it’s simple and efficient, and avoids being really stupid. Except for the WTF resolution. Not in the same pool as Jaws, but a diverting night at the movies for fans of the genre. Japanese title: Lost Vacation. (86 min)
