I can't say much about this film. I think it speaks for itself (as do the current ratings on here). I rented this about two years ago and I totally regretted it. I even /tried/ to like it by watching it twice, but I just couldn't. I can safely say that I have absolutely no desire to see this waste of time ever, ever again. And I'm not one to trash a movie, but I truly believe this was awful. It wasn't even funny in the slightest. The only bits I enjoyed were the few scenes with Christopher Walken in them. I think this film ruined both Jack Black and Ben Stiller for me. All I can think of when I see one of their films now-a-days is this terrible movie, and it reminds me not to waste my money. Amy Poehler is so very annoying, too.
Overall, well, I think you get my point. The stars are for Walken, by the way.
