The original pre-cert videotape of this changes hands for crazy money these days, it's very very rare. I was 'fortunate' enough to get hold of a DVD-R of this, as it sounded right up my street...
And the verdict?.....Jeeez! As noted previously, this is definitely "inspired" by 'Last House On The Left" but the tone is totally different. It's proper early-70s rough-ass grindhouse business, sexist as hell, dumb, with sub-porno standard acting. It's not disturbing in the slightest however, and whilst the subject matter (rape rape and more rape) is nasty, the way it's done is just funny. The soundtrack is absolutely wild - incoherent hippy wailing over acoustic guitar meandering, you couldn't make it up, honestly. Has to be heard to be believed.
This is a great period piece...the work of anonymous drunken old hacks exploiting the hippy counterculture. God knows who any of the people involved in this are, but hell, I'd be fascinated to know how and why a movie like this came about. Worth seeing to sate your curiosity...this film is one of a kind. It is DEFINITELY bad though.
