I saw a sneak preview (my b/f's friend works for Universal Pictures) of this last night and it was really funny!!! We agreed that it was a lot better than we thought considering the cast of relatively unknowns. I also just realized today that the lead in the movie is in the current Mac campaign where there's the PC guy and the Mac guy....he's the Mac guy. Anyway, I recommend this movie if you're looking for a young-ish type comedy.
ETA: there's also stereotypical Greek humor in there, but nothing too bad. My favorite is a scene where the pledge talks about wanting to wear visors tilted a little bit to the side and use hair gel like the brothers....haha.
