Interesting subject, needless imagery
The basic concept of this film is quite interesting, looking at the events from the terrorists point of view is actually a commendable and thought provoking direction to come from.
I just have one serious problem with the film, the constant interefering and needless footage of the Twin Towers being hit and destroyed. It simply wasn't needed, if Michael Moore can make Farenheit 9/11 without a single shot of the towers, then so can these guys. Its there for nothing more than impact in a film that on the face of it may have been quite boring without it. If the last shot of the film had been the guy walking onto the plane (as it was) with no previous footage of the towers, the impact of that shot alone would have been incredible.
In conclusion, interesting story and approached well, but needless shock footage ruins the film and its credability.
