I saw it the day it opened.
It was obviously designed to make you feel as if you are THERE. It ends looking out the cockpit as they struggle for control of the plane. The ground comes up and then at the moment of impact goes to black. You die with them.
There has been much talk about this movie being propaganda or speculation or even exploitation.
I don't think it was. If anything it was completely devoid of commentary.
Obviously there was some speculation as to the events on the plane in those final minutes. All the info we have (unless you are convinced that everything the "government" tells us is a lie) was from phone conversations with those on the ground and the data from the inflight recorder. All depictions of the individuals were made based on extensive research on these folks with input from their families (probably not the families of the terrorists).
As far as I know, everything that was depicted was tied to some information. Any events that were speculated on appeared to me to be completely plausible and even likely. Ultimately it was a "best guess" as to what really happened. But anyone who would complain about it would have to provide a better explanation based on some verifiable fact. Quite a challenge indeed.
And ulitmately what does it matter. The plane went down before it hit the capitol building. Unless you are convinced that the plane was shot down by the "government", you have to acknowledge that however successful they were, these folks are the reason why.
Rest in peace, and thank you!
