Query: Disappointing

The general idea of this dumb teen comedy is that a group of three friends have been broken up by one of the friends' girlfriend. I watched this movie because I'm a fan of Jack Black, but this movie doesn't work on so many levels. First of all, you never really get the feeling that the friendship between these three friends is really very strong. So when they start kidnapping and planning murder, you don't really understand why they're going to all the trouble. Another thing is the obsession with Neil Diamond. It's never really funny and it just falls flat. Third, the chemistry between the supposed romantic interests is terrible. The characters are all supposed to be in such deep love, but you never see it in this movie. If you're interested in comedy, you can find lots of better movies than this. For Jack Black fans, head for High Fidelity, or School of Rock instead.
