I loved this movie, it was really funny. I haven't laughed this hard at a movie in a long time. It started out a little slow, which scared me but it picked right up. It's weird watching a comedy in a theater with 20 people in it. It's easy to laugh at a movie when everyone does, it takes a good film to laugh when you're the only one laughing.
I won't ruin any of the movie for you, but I will recommend that go you see it. It's definitely worth the $7! It's worth a LOT more than that if you get all the inside jokes that are in the flick. If you've listened to the commentaries on the Kevin Smith DVDs it'll be that much funnier. And stay through the credits. They're funny too :)
