We used our entertainment movie and meal deal today and decided to see United 93 at Universal. My comparison is, that they are both overwhlemingly sad. A & E's Flight 93 was much more focused on the families left behind and getting to know the passengers. They seemed to stick with what they knew, from phone conversations.
United 93 was more about the flight controllers on the ground, more about the stabbing and anger of those hijacking the plane (and I'm not sure how they knew about many of these things). It was very much more intense. There were sobs at the end of the movie, and a couple of people couldn't get out of their seats, because they were that upset. I won't say much about the end, but even knowing how it ended, it was so intense, you were silently routing for those trying to take back control of the plane, to be successful.
They both told the story, and I preferred (if there was such a thing) the story as told on A & E. It just seemed to put you closer to the people, and didn't seem to be sensationalizing, but just told the story. It seemed the allotment of time for each movie was spent differently. One focused on the families at home, and passengers and their communciations with their families, while the other put more emphasis on the air traffic control, and military and their confusion and miscommunication, as well as the in plane attacks by the hijackers.
