I saw this film on opening day with a friend because I was bored, and did not expect much. After seeing the trailer I thought "this movie will make me laugh a bit, but will probably suck overall", and I was mistaken. I was pleasantly surprised by how funny this movie was surprisingly funny. I am not a big Seth Rogen fan, but he was funny. The biggest stand-out performance was from Zach Effron. He has come a long way since being a Disney star, and he was the reason for a good number of laughs I got from this film. I see a lot of reviews on here complaining about how dirty and vulgar this film was... did none of you read the rating? This movie is rated R for "pervasive language, strong crude and sexual content, graphic nudity, and drug use throughout"... I mean, for God's sake Rogen and Effron get in a dildo fight(which was hilarious).If you are offended by such things, a prude, or easily offended in general, you probably should not see this film. If you do not care about that, and expect a fun movie full of laughs, cussing and partying, this is a film for you. Hope you enjoy.
