Selena Gomez, Rachel Korine, Vanessa Hudgens, and Ashley Benson in Spring BreakersSPRING BREAKERS

At the screening of Spring Breakers that I attended, I counted eight viewers who walked out of the movie, and stayed out, well before the end credits rolled. In all honesty, I'm amazed the tally wasn't higher than that. The movie being touted in print and in trailers promises a rowdy, randy romp in the sun with built-in audience-grabbers: Disney princesses acting nasty! James Franco with cornrows and grillz! But the movie that writer/director Harmony Korine has actually made - despite, indeed, its also being a rowdy, randy romp in the sun - bears so little relation to its cheeky, borderline-innocuous advertising campaign that patrons can be easily forgiven for feeling badly misled and deciding to bolt. It would be like going to see Dumbo and instead getting Gus Van Sant's Elephant.

Jerry O'Connell in Piranha 3DPIRANHA 3D

Alexandre Aja's Piranha 3D puts you in the unexpected position of actively rooting for the piranha, not because the effects are all that great (they're actually pretty awful), but because more flesh for the fish means fewer irritating humans to put up with.
