Yeah, I know what you mean. You have to go through five break-ups, four divorces, three suicide attempts and two existential crises to even begin to understand his movies.
I can't say I'm a fan. I don't think you can be a fan of his art, any more than you can be a fan of Kierkegaard. Bergman is frightening. He has seen farther and deeper than most of us have, so he shows us life in a light that we are not ready to accept. It's too dark, too complicated, too strenuous, too much filled with anxiety.
Woody Allen is more palatable. I think of him as a sort of Ingmar Bergman gone to Hollywood. I am a fan of Woody Allen.
