I've read most of the comments here. I came to the conclusion that almost everybody agrees that 9/11 is a shocking piece of history. There are a few who think that the added narrative is weak and

I agree that the narrative is weak and unnecessary. About two brothers finding each other back after the disaster and the cliff hanger about Tony. But I don't think narration is unnecessary. Like I lot of theorists I think that our own lives are narrations. We are living and making our own autobiography. So if we tell about our lives this is always in the form of narration. We don't sum up facts like: Birth, Childhood, High School etc. We create a story about our live.

Because we are familiar with stories, we want to put history in a story as well. Because in the form of a story we can identify ourselves. We can better understand the things happened in history when its told in the form of a story. So that's the purpose of adding a story in documentary. The story is weak, so be it, but we understand whats going on. If it was me out there I would be worried sick about my brother.

And the second point, making a blockbuster movie about it. True, it's been to recent to come up with a big movie about 9/11. Though, there have been a few about the subject, but none of them like this documentary. But what if there will be a movie in about 5 years? I agree it is wrong trying to make a lot of money out of 9/11. But I also agree that movies are one of the best way to tell history. How many movies about the World war 2 have we seen? If I had not seen these movies my view of the WW would me totally different. I remember seeing Schindlers List, and I cried for an hour during class. Movies give you a good image of the things that happened in history and although it is fiction it contributes to the memory of the disasters and the casualties.

So my point: telling stories is not always bad, it makes us identify with the story, and makes us never forget what happened.
