Forget the horrible 3D conversion, the lack of decent writing, the script continuity issues (Elizabeth Shue getting out of the lake sopping wet one minute and completely dry in the next shot) and the relentless college students jumping up and down to house music on boats in a corner of the lake....this movie's worst offense? It's BORING. Nothing happens for the first 70 minutes that's even remotely interesting, and by the time you see a CG severed penis get eaten by a Piranha in 3D right in front of your face, then burped back out, the reaction is less revulsion and fear than "Really? That's the best you could do?"
