Just got back from the screening. It's pretty good. I didn't like it as much as Old School, but it is worth checking out. Zack is definitely the funniest actor in the movie. He just plays an unstable goofball trying to fit in to perfection. There were some not so funny scenes and some scenes that went a little wacky that just didn't work, like the Chinese mobsters and the whole "I am Doug" (you'll know what I'm talking about before it happens, which is never a good thing). There are a few really great laugh out loud moments though. The Mike Tyson cameo is played slightly out of context in the trailer, and I promise you it's WAY funnier in the movie, and Heather Graham was a highlight. The explanation for how the tiger got into the bathroom and the whole wedding ring fiasco are the funniest bits. I give it a solid B.
