Could have been better
To be honest I had to stop watching this documentary because it was too much to watch. And I believe that the makers missed a great opportunity to make a great documentary and fell into the same trap that all other 9/11 docos seems to make.
Why the dramatic music and shots of the towers? Why do 9/11 docos seem to want to forcefully convey the horror of that day? I GET it! I saw it on the day, I've seen it in other documentaries. I GET that it was awful for those directly involved. What I don't get is why it was relevant to this documentary.
It detracted away from the achingly beautiful, bittersweet, sad, emotional, scary and loving things that people were saying about their loved ones they lost that day. These people had amazing things to say, a real testament to the human spirit and how people convey their love. The choices of people trapped in the towers was intriguing, and so obvious too (I like to think that I would have phoned my daddy straight away too).
If you can deal with the overly-dramatic shots of the tower (especially the ones with the labels as to where people were - you could have used pictures of the towers not on 9/11!) and the intense music there is (from the bit I watched) a lovely documentary hidden in here.
