Doug Benson ruined this movie
I've had to deal with this guy in person, and let me tell you, he's an annoying, immature, petulant little baby. That'd be OK if he was funny, but that's the worst part, he's not.
He doesn't understand that he's being made of fun of in this piece, so he runs around doing unbearably lame standup (well, better than Bobcat Goldthwait, but not by much).
I just had the displeasure of having to watch his act again (business thing), and it really varies on how high he is. In this case he was just completely unfunny and worse, abusive to to the crowd. And not in the "shut down the heckler" sense: the crowd eventually begain to ignore him, so he was screaming at some girls; fortunately the guy at their table shut him down. I thought Doug was going to cry, but he just went back up and squinted his way though the rest of his monotonous material.
