I went to see the movie "United 93" tonight and I thought that it was a very powerful movie. Given that there is little that I didn't already know, it was surprising that the movie could not only hold my attention, but that it was so riveting. The first half of the movie was a little slow at times, but the last half more than made up for that. The only change that I would have made would be to include a clock such as the one used in "24" or "High Noon." Not so much for suspense, but so that viewers would have some perspective on how little time different people had to respond to what was happening. There may have been just over an hour from when the first plane hit the towers to when United 93 crashed and less than one hour between the second plane hitting the towers and the crash of 93, but The people that I went with didn't seem to remember that and the film didn't make that clear enough. The reaction was one that the people running air traffic control and the military were incompetent, but I think that if people understood how little real time was involved, they would have been far less critical. It is the only movie that I have been to where i had no idea of the names of virtually any of the characters all the way through the movie. More importantly, not knowing the names didn't matter. Anyway, I would give the movie a strong 4.5 out of 5 stars.
