I saw the movie on Thursday.
I thought the actors did an incredible job. I got chocked up right from the beginning of the movie. Thankfully, Oliver Stone didn't attempt to recreate the plans crashing in or the towers falling. He relied strictly on CNN clippings (which would have been all the wives and family would have seen).
It is amazing that those men survived not only the first tower going down but then the second and WTC 7.
My only issue, which wasn't with the movie, it was with someone in the audience, they brought their like 7 year old to the theater. Of course this kid had really no idea what the hell was going on. The kid kept asking questions (quite loudly). I just thought (and still do think) that WTC is a completely INAPPROPRIATE move to take a 7 year old to. The kid was only like 2 when it happened, so he/she had no idea the hell people went through. For me it was laziness on the parents part. They wanted to see the movie, didn't want to find a babysitter and took the kid to a movie they shouldn't have been seeing. God, if I had seen this movie at 7 years old, I probably would have had nightmares. End my rant.
