I hated this film at first. Seriously. I thought it was so dumb, to the point where I thought it was trying to be dumb, and so I scoffed and looked away. Then, some time later, I watched it again, with friends this time, and I saw for the first time the true genius that is Seann William Scott. This film is comic perfection, as quotable as Napoleon Dynamite, except nobody ever quotes it so it's not nearly as annoying. My favorite conversation is 'Hey look, a barn!' 'Is it red?' 'No.' 'Then it's not a barn!' Right, I know, not that funny in writing, but in the context of the movies, as with most quotes, it is hilarious.
Don't be lame - don't listen to those who are too cool for this movie, as I once was. Embrace it, and just laugh.
