Seeing and hearing all the accolades for this cable pioneer was really interesting, but as I said this probably would hold little interest to the casual film viewer who could care less about Truffaut, Berman or Antonioni (among others). However, what becomes fascinating for ANY viewer is the man himself. Harvey was a very disturbed man who had a lifetime of demons and personal baggage--so much that he ultimately killed his wife and then himself. The film's examination of why this occurred is interesting, but also very unsatisfying because so little is known about his childhood. His two sisters killed themselves (though there is a tiny doubt about what happened to one of them), his father is dead and his mother is very emotionally constricted. So the film chooses to spend much of its focus on the impact of this murder-suicide on those who knew him. What I appreciated was that although many voiced their sadness at his passing and talked about what a great person he was, some others (particularly in the very end of the film) were understandably angry about what he did and find it wrong to elevate this guy to sainthood--after all, he did murder his wife. As a psychology teacher and ex-psychotherapist, this reaction is by far the most fascinating part of the film.
By the way, although this is a wonderful film, the film maker Ms. Cassavetes chose a lot of clips for the documentary that are NOT family-appropriate. While there's quite a bit of nudity, most of it isn't salacious and is from art films. However, some of the scenes are borderline pornographic and the scene of Rutger Hauer masturbating makes this a film you DON'T show your kids. Too bad the film included one or two of these clips--it might alienate some in the audience and wasn't needed to tell the story.
