I just saw it about 30 minutes ago. This movie, if you didn't know, is about September 11th focusing primarily on flight 93.
For starters, the movie wasn't bad. It had some real footage of the plane crashes into the World Trade Centers which kind of made the movie seem more real. The actual story was kind of slow at first and picked up towards the very end.
United 93 was the only plane to not make it to its destination, which this movie made an attempt to show how that came to be.
I can't think of anything else to say about this movie that doesn't ruin it...... If you want to find out more, you can always go see it.
