At once self-conscious and generic, this smart monster movie about smart monsters—supersharks cleverer than the scientist who created them—repeatedly lulls you into thinking it’s paint by numbers. But the writers know you’ll know what to expect. The characters are sufficiently naive to get picked off one by one, but their ignorance doesn’t extend to the genre conventions governing their behavior, making for some shockingly funny moments. The furious, expressionistically blood-drenched action is set in and around an oppressively self-contained floating laboratory that seems designed—like the mountain hotel in The Shining—to test its inhabitants’ vulnerability. Expect to be frequently reminded of other movies—that’s part of the point. Renny Harlin (Cliffhanger) directed a screenplay by Duncan Kennedy, Donna Powers, and Wayne Powers; with Saffron Burrows, LL Cool J, Samuel L. Jackson, Thomas Jane, Jacqueline McKenzie, Michael Rapaport, and Stellan Skarsgard.
