The movie wasn't as funny as the regular series' shows, IMO. I still thought it was funny, and was pee-my-pants-laughing in a few parts. But, for making a "OMFG, JACKASS THE MOVIE!", I thought it was kind of filled with too many "meh" bits.
You know a movie that totally caught me off guard because I thought it would suck, but wound up being pretty damned funny was Wedding Crashers. Not bad at all.
