Well. The Bitches. Okay, here's the basic plot synopsis. Two girls are in a sparsely furnished apartment scandily clad and being generally unpleasant to each other. A guy comes in, and they start to engage in, um, fun. Then the fun turns on itself as, uh, you'd have to see it.
But you don't need to. As with all Richard Kern films, if you've seen one, you've seen them all. They're simply variations on being shocking in different ways. Is there symbolism in them? Nothing above the kinds of things a 6th grader would get, and a 6th grader sure as heck shouldn't being seeing this. It's really more fascinating as a documentary of people doing things to/with/on each other.
On the upside, the music is fantastic. Honestly, this is worth watching just for the excellent music (the composer escapes me at the moment). It seems to have very little connection with the film, but definitely works. Imagine Foetus' agro-jazz stuff gone more jazz and you sorta have the idea.
Enjoy.
