I take it you haven't seen it?

It's completely low budget pre-South Park days stuff from Matt/Trey. If you like their other stuff, you'll probably find this pretty damn funny. Basically a cult movie at this point, really.
The deal with the disc was it never saw a DVD release after its theatrical run about 6 years ago, then was announced a year or two ago as a 2-disc SE, then the company publishing it was engulfed by Universal, and it's been in limbo ever since. It still has a lot of the features, including a drunken commentary from Matt/Trey, so it should be a nice treat to finally have.
I've had to make do with a UK PAL version for the last 4 years and it's bare bones.
