I saw this movie Saturday night. As Cidp24A said, all the funny parts are in the trailers that have been on TV. It was predictable, silly and crass.
If you're into silly, not funny, this is your movie. Personally I wish I had waited for it to come out on cable and watched it one evening when I was bored.
