Saying it's "offbeat" would be an understatement. Antimatter is an obnoxious bum, but some of the things she says are almost profound; it's a peak into a kind of hyper-reality world of punk. Like I said, it's not for everyone, but it's such an unusual film, that it's worth a peak just to see if you like it.
BTW, be prepared for some nudity; if you don't like fat women...you've been warned. THe music is surprisingly decent too as are the performances. It was on Netflix but i don't think it's in their lineup anymore so i don't know where you'll be able to see it, but again it's worth a peak.
