The New York Press (an alt-weekly from NY for those not familiar) has a long and in-depth article on the partriotism of recent movies. The article focuses on two documentaries, Gunner Palace and Operation: Dreamland, both of which examine American military personel in the Middle East. Within that, though, movies like War of the Worlds and Spider-Man 2 are touched on as examples of how we as an audience view violence and heroism since September 11, 2001. In short, these movies are seen to be a sort of group therapy, allowing the audience to work out it's issues with what happened by reliving that that sense of terror as a form of catharsis. It's a good read and highly worth checking out.
