I had a different expirence. It was solid, but ALOT of jokes fell flat. Alot of "who's that one guy laughing at that joke 2 rows up?" moments. Not in league with 40 Year Old Virgin or Old School, imo.
Anyways, I recently watched Brick and Luck Number Slevin. Great films. Slightly predictable, but enough turns where at least some of them will get you.
