I recently rented Fog of War from Netflix and was impressed by a couple things:

1. Through clever use of music and stock footage, the filmmakers were able to leave all the narration to McNamara, who had a very engaging narrative style.
2. Villain documentary is interesting--I read the autobiography of Joseph Haldemaan, Nixon's chief of staff, and found interesting levels of self-justification and self-blame. A similar situation occurs here: McNamara is pretty blunt about the mistakes they made, but he still comes out looking good.
3. He seems to doubt that Agent Orange hurt anybody.
4. Throughout the movie, I couldn't help but think of Ted Steven's vigorous defense of his pork-barrel bridge boondoggle. I say NO!.
