I can see anticipate the detractors complaining about this film; the lack of dialog, music, narration, captioning etc. However I don't share their opinion. This was one of the BEST `documentaries' I've seen. I say this specifically because of the lack of voiceovers, and the general toning-down of footage common in the aftermath of 9/11.
As a witness it's important to me to see the events unfold in the same way they unfolded that day; without narration, without music, without handholding. I wanted to re-experience the feeling of staring at the building(s) focusing on MY OWN thoughts and listening to the sounds as they actually happened.
I realize that narration is important to some people who aren't from New York and want a more `fact-based' kind of documentary. Those documentaries have already been done. This was a refreshing and excellent chance to meander through that day and imagine what would be going through your own mind instead of having a viewpoint imposed.
