There is nothing really wrong with this documentary. We go through his career and he tells us what happened on every set. But that's it. What would have helped this immensely would have been other directors and actors telling us stuff about him, about who he is. We never get that. Why is he so facinated with brutal scenes which is a recurring theme. Besides his directing style of steadycam shots and long shots we never get to know who De Palma is.
