Is this comment at The Atlantic's site, which was written in response to Brian Mockenhaupt's story What's Wrong With 'The Hurt Locker'. I couldn't agree more, or have said it more succinctly.
"A lot of movies attempt to show the emotional effects of PTSD (e.g., "Shutter Island"). "The Hurt Locker" is intended to have the audience actually experience PTSD (JW note: that's post traumatic stress disorder). That's why it strings together sequences of excruciating tension, like the sniper business. The scene in the grocery store (which this reviewer approves of ) would not work nearly as well without following the incessant stream of adrenaline-pumping scenes that come before, which are selected to build and release tension, not serve as reportage. Everything in the movie is intended to elicit an emotional, not an intellectual, response. And it works beautifully."
I wouldn't volunteer to watch the movie again. But it was damn good for that very reason -- it was a precise and powerful film that made me (and the folks I watched it with) feel disoriented and afraid.
