In my humble option this movie is far more accurate and believable than the 1976 film. There is no back-story drama to speak of and there aren't a bunch of fictional characters. They tell the story with the real people who were involved. Personally, I wasn't very impressed with the 1976 movie and as a student of the event, I am really glad a more accurate depiction was created. Someone called it the shortest 2.5 hours he had ever spent in a theater.
