I didn't have high expectations for this movie so I was delighted when it proved to be funny, clever, and well-made. The actors do a great job and the dialogue is totally believable; despite the pot-smoking and lax  attitude of the teenagers, the swearing is relatively limited, which I  always think of as a sign of a good film. Don't get me wrong - this isn't a  great film, it's silly schlock - but it's entertaining, fun schlock.  Watching the film with the audio commentary by the director and two of the  actors (after you've seen the film straight through the first time) is a  blast and a half. Definitely worth getting on DVD just for the audio  commentary. Reminds me of a combination of Half-Baked, Clerks, and Evil  Dead 2.
