It's almost impossible to describe WeirdTV. It's the kind of show that you either loved it or hated it, and if you loved it, odds are you have quite a few problems.
WeirdTV was a collection of weird segments and captured events such as the Burning Man Festival. There were a few recurring segments on the show, such as Shadoevision, etc. Sometimes the show made you think, sometimes it made you cringe, but it almost always made you laugh. It's a real shame that it was cancelled. I believe you can still stream some stuff from their site. If you find any tapes in a movie store or a bargain bin of some shop, I recommend you snatch them up!
