This is something that only could have been made in the early 70's. Its more of an acid trip than a movie. I wouldn't be surprised if this had been shot as a full on porn but then cut to be released as "art" when they realized how bad it was. It actually makes it funnier to have these abrupt cuts in the very, very un-sexy sex scenes. The film stock looks burnt and scratched most of the time and there is no audio for the actors, its all voice over narration. Low budget and amateur to its very core.
But, I'd always rather see something that sucks because its so weird that sucks because its the same as everything else - that's why it gets a 5.
