It's a horror comedy, with all the emphasis on the comedy, and deliberately done as a B-movie. The 3D gets some abusive camerawork at the start of the film, but it's generally used with more grace than most 3D B-movies bother with. The plot is dumb, but it's a remake of a cheesy knockoff of Jaws (complete with Richard Dreyfuss in this remake), so you knew that. Considerable T&A for the heterosexual male demographic, and gore that's one part gruesome to three parts silly fun. Score: 3 stars out of 4.
