It was very moving. Depressing and motivating at the same time. It's a good reminder of what we're up against, that our enemy wants us all dead. As such, I believe they should show this movie on network TV during prime time hours.
It was filmed in real time, from takeoff to hijacking to crash. You can feel the tension build. Your heart goes out to the innocent people the terrorists butchered. The whole movie is two hours long, but it felt like double that watching from the audience. It was wrenching, and the confusion and disarry the various gov't entities were hamstrung with on the day in question is flat maddening.
The libs are all freaking out because they realize this: any clear thinking American who goes to see this movie will come away from it reinvigorated in his/her support of President Bush and the War on Terror.
I don't really believe in conspiracy theories surrounding 9-11, not involving this plane or the one which hit the Pentagon, AA 77. The cockpit voice recorder in United 93 is said to have captured Scott Beamer and other passengers wrestling with the hijackers and forcing the plane to crash.
That said, I will admit there are some things that cause people to question what happened.
Anyway, go see it for yourself. It's worth the price of admission, a movie you'll have to walk off when it's over...
