United 93 IMO is the best 9/11 film, second only to the documentary that was made as that horrible day unfolded, "9/11" by Jules and Gideon Naudet. Paul Greengrass directs the action and the actors with expertise and the result is an all too unnerving sense that you are THERE, in that metallic tube, too far up the sky to escape, and contemplating your mortality. It's claustrophobic, abrupt, violent, desperate, and unbearably sad. But a big reason why I enjoyed the film as an actual entertainment experience (I never feel comfortable calling 9/11 movies 'entertainment', but...) is that the viewer gets a decent summation of each terrible insult of that infamous Tuesday morning: The Boston Centre's first clues that something was amiss with American flight 11; The horrific realisation that, only moments after United 175 had offered assistance to the ATCs, it too, had been hijacked; The collective global trauma inflicted as 175 smashed into Trade Centre Tower 2 on live television, including the BBC; The damage and death at the Pentagon when American 77 slammed into it, even if flight 77 was only spoken of as the passengers of United 93 communicated with their families on the ground. I've watched several 9/11 themed movies; Oliver Stone's World Trade Center isn't bad per se, but because a lot of it took place under the rubble of the collapsed skyscrapers, it needed to be dark. It was a great story of survival, but somehow, I couldn't "like" it because I couldn't see the 2 main characters. I've seen sincere, sappy, disrespectful and just plain boring films about 9/11. United 93 is definitely the best one if you want a non-sentimental, fast-paced, realistically acted fight to the death.
