Tarkovsky belongs in the pantheon of European art cinema that influenced Woody Allen. The blatant narcissism in this film is explicit in many of Allen's films. But unlike Allen who is a comedian, Tarkovsky had no interest in helping the audience follow the story.
Extreme story, inspiring and also warning. We ought to find the courage and use it in a responsable way. No matter how lonely you feel, you don't live alone.
