As a fan of most of Jack Black's work so far (at least the non Tenacious D stuff that is in comedy) and a fan of Michael Cera's great straight man work on Arrested Development and Superbad, I was very disappointed in this film. It is a great premise for a movie but it fails to deliver many laughs, it is basically one of those "all the funny parts are in the trailer" movies and was I think a really wasted opportunity for what could have been a very funny film. Jack Black is okay doing his usual act and Michael Cera is very good in his typical straight man role but the laughs don't exactly come flowing through. There are a couple of very good cameo appearances in the movie, I don't want to spoil the surprise, and they help to make up for the overall poor quality of the rest of the film. Worth seeing probably but definitely not at the movies for $12.
