All I can find out is that the documentary hasn't been released yet. According to an interview with the makers of this documentary, it intended to give us info on how the enemies in Iraq work, their tactics, and their motivations. In that regard it may be a useful thing to watch - as a way to better understand the enemy and so better able to defeat them. Also, I know why you call them terrorists, but these enemies appear to be directing their attacks and IEDs towards US soldiers and Marines. So in that regard they are classical definition of insurgents. They aren't willy-nilly bombing citizen neighborhoods, they are intending to hit military convoys and military patrols.
