I watched it yesterday, too. I can understand RRA's point, but the story was about these two men and what they went through. Stone wasn't telling the story about the others.

Seeing it was emotionally wrenching, the shadow of the planes overhead, the confusion, the original certainty that it must be a small private plane that hit the tower by accident. It was like reliving that day all over again.

If a film's success can be measured by how it moves you, then this one definitely succeeded.
