“We can't just wait here for sharks to rain down on us.” Indeed. It's raining man-eating sharks on LA surfers. Caused by a freaky tornado. The whys and wherefores are a bit murky. Last year's Bait was much more fun and, crucially, funny. Poor John Heard (Big, Cat People) doesn't survive past the half-hour mark in this dull B-movie where the surfboards out-act the confused (including Tara Reid) cast.
