The Postmodern in the first 10 Minutes of "Super Troopers"

The first ten minutes of Super Troopers are so brilliant. Only when I'd watched the whole film did I understand it, and thanks to the drugs I'm not 100% on the point of view and what "really" happened. What about the other Broken Lizard movies: are Club Dread and Beerfest any good? Glomer?
