For me this is the best documentary about 9/11 until today. Other documentaries make analysis more cold and rational about the attacks, and has its great importance, of course, but this one is 100% immersive because it shows the point of view of those who felt the terror in the skin, without the need for any narrator in the background explaining the events. This is the strength of this documentary: the images and the reaction of the people speak for themselves. It gives the sensation of fear, confusion and perplexity that the people were feeling. Even if you're not a North American, even if you live in another country far this tragedy, when you watch this documentary, you have the full feeling that was there that day. A very impressive and impactful documentary.

I am literally in awe of this film. The dynamics are so extreme, the images not only heartbreaking and historic, but the definition of a tragic day that defines a generation. While difficult to take it all in, you can not take away from the heroes, the struggle people went through and the sheer collective overwhelming sense of panic and loss. It is as though you are there, but witnessing it from afar. I can see why this won all four of it's Emmy Awards, especially for the editing and sound editing and mixing - all of which are nothing less than top notch. One of the best made films of the year. This film captures the humanity as well as the force and power of science. When it tells you to move, you move. The pace of this is a phenomenal display of the events it shows. Bravo!

There have been many documentary about 9/11 since the attack. This one took the idea of the TV show "24" and showed the events from seconds after the 1st plane hit up to about 100 min thereafter in real time. The footage used were mostly from personal camcorders, and some from TV. The audios were either directly from the camcorders, from the media coverage or phone conversations sound bites at the moment. What was interesting about the documentary is that the point of view is not at the Twin Towers, but away from the Twin Towers. You see people in Time Square watched it on the outdoor large screen. You see students watching the event from Stevens Institute across the river in Hoboken, NJ. You see how people reacted in their apartments far away from the Twin Tower. In a way, the documentary is not just about 9/11, but an anthropological view of the people's reaction upon crisis. The editing job of putting all these material together was superb.

102 minutes that changed America is a totally engrossing documentary, focusing on the attacks in New york in real time. Much of the footage has never been seen before. It captures perfectly the terror, chaos and confusion of that morning, using police and fire department radio calls, 911 calls from people trapped in the towers and of course video footage from news cameras and people in the street. The most amazing moment is filmed from an apartment several blocks away. As two women talk off camera, the second plane flies into the second tower. The screams of horror and disbelief that follow are just incredible to hear. Unmissable.
