First the good news. I had seen the original, unedited version of this film and was impressed by it's sheer animal intensity. Basically a film combining music with sexuality, the music fed the explicit sexuality and vice versa. Once one recognized that the minimal plot (and by minimal, I mean that a Dr. Seus book would be Tolstoy in comparison to this screenplay) is simply a framework upon which to hang the interaction between the sex and the music, the film can be quite compelling.
Now the bad news. I purchased the imported DVD from Amazon to find that it was in fact an "unrated edited version" and that virtually all scenes of explicit sexuality had been cut, obviously to conform with whatever obscenity laws/rules impact the distribution of films in Canada and the USA. In doing this, the intensity and power of the film which led to the standing ovations at Cannes is gone. Instead, what one is left with is basically a softcore porn film with better music.
If you can get your hands on a copy of the unedited theatrical version of the movie, it's worth purchasing. Otherwise, if you end up with the edited version, there is a feature that allows you to play only the music scenes from the film. Do yourself a favor and view that, or better yet, buy the soundtrack on CD.
