IHTSBIH is without a doubt full of humor and debauchery. If you read the book and liked it, then you should know what's in store for the movie.

My wife laughed so hard she peed herself (although in fairness, she is pregnant). Not even kidding. Awesome movie.

Tucker Max isn't for everyone - prudes and those who generally refused to have fun in college probably won't like him. All the bad reviews I've seen either complain because they can't take a little off color jokes and nudity, or they have a tinge of envy. To those who say he isn't believable, I beg you to come to my college. It was a great movie from start to finish, the characters were believable yet funny, and the story took a much more realistic turn then most comedies will dare. You won't need willing suspension of disbelief for this movie like you need for a lot of others, and you won't see anything like this movie in a while. Worth the trip, I'm going to go see it a 2nd and 3rd time.

the best movie ever made

Simply put, it's a great movie. The humor requires no suspension of disbelief and does not insult the intelligence of the audience. The movie also has an actual story rather than a bunch of jokes loosely tied together by some narrative. Everyone in the theatre seemed to enjoy it and most laughed throughout the whole thing. It's probably not the movie for you if you're easily offended, but if you have an open mind and are just looking for a good time, go see it.
