Movie recommendation by Thomas

I watched a movie last night that was recommended by a friend. It is actually the documentary (academy award 2004 for best documentary):
The Fog of War.

11 lessons given by former Secretary of Defense Robert McNamara. After watching it, I feel very scared about what is going on today with Iraq and even Iran. I should say I am actually disturbed as I feel that no one really learnt from the past mistakes.

For the ones who have seen it, what do you think about it? For the others, go rent it.
