I've been a Michael Cera fan from his days in "Arrested Development", and this movie really let me down. While I don't blame Cera for this flop, I was a little disappointed in his role in the film. I personally don't think that Jack Black has what it takes to be a leading man in any type of film. This film has it's funny moments but for the most part it's just them beating a lame joke to death, trying to make it funny. Save your money, or go see "The Hangover" if you want to see a funny movie.
