After reading the book I literally counted down the days to this movies opening. The movie takes such a small piece of the book that it almost doesn't do it justice, but they can't be blaimed, they needed to make a movie out of it. All in all, a fun movie to watch, especially if you've read the book.
I recommend you read the book, or at least listen to the audio tape. Its read by the real Tucker Max and is absolutely hilarious. I embarassed myself a few times on airplanes and other public places I was laughing so hard.
