I will definitely watch this movie opening weekend. And I go to maybe one movie every 2-3 years. As painful as it may be, I think most Americans need to see this movie. For those of you who lost loved ones, you don't need a movie to remind you of that day. But I fear millions of Americans have forgotten (to some degree) how they felt that day.
Also, I understand that the movie is as accurate as possible. The surviving families all have signed off on it, and it's not a "Hollywood version." Therefore, I think we can all learn something and be uplifted by the actions of these brave people.
