I watch this film once a year. Forget about Stone's theories and jumps of faith and just look at this as a thought provoking piece of cinema that demands the viewer to sit up and take notice of it. You may agree or disagree with the director's approach to the material and the artistic license he imposes, but I'm in no doubt of the films power and billiance just on an artistic front.
It's stunningly filmed and edited. Just a superb piece of filmmaking, whether you agree or disagree with Stone's conclusions. And hey - if you don't agree I defy you not to look it all up afterwards. That's the brilliance of the piece.
