I have just seen UNITED 93. Frankly I have no words to describe it. It's not even something that one can crit in deapth, because the happenings that unfolded in the film actually happened.
Right from the beginning of the film, I felt on edge. It's like I was waiting for something to happen, but you just never know when the terrorists were going to strike. I loved the reality of the film - everything was so natural-looking ....from the people's appearances to their mundane conversations. I especially appreciated the passenger's reactions to the attack on board.
There were no 'heroes' so to speak. They were all completely normal and responded to the situation like any average person would (this is, of course only my opinion). In short, I think Greengrass has done a superb job with this film.
