You're going to judge an entire movie by an 8 minute trailer?
No, you are missing the point. The point is that Hassan is the central character. He is the one we observe through the life of the film...and his motivation to take his actions, whatever they are, are generated on false pretenses, that he was kidnapped and tortured by Americans (through a Paki proxy).
One of Schlussell's points is that this false pretense is not a good basis for the action in the film. And I think this is a valid point. Instead, it tries to plan the age old argument of "America made them through America's actions" as opposed to the jihadists making themselves through a corrupt culture and taking on a violent religious POV.
The producers of the film seem to have the mantra "we must know our enemy", but Hassan's motivator is not the motivator of our enemy, though they would love for it to truly be.
I do plan to go see it, for it did look like the acting was credible, and the subject matter disturbing enough to provoke thought, but based on what I am seeing as indicators for Hassan's driving force, I would hope people would acknowledge it as flawed, for I do believe it is.
