my gf and i went to see this tonight. it was really good. it is documentary style, and really gives you an insight into what really went down in the plane (as far as anyone knows) and on the ground, with the FAA, air traffic control, and military interaction. it was a very good movie, and even though it is such a controversial issue producing a movie about this event, it is definitely worth seeing.
and for my personal thought post movie, without ruining it, is damn if what was shown really happened on the plane and was pretty accurate, just wow i cant believe that. just sickening, and so sad how it ended. watch it, you will like it.
