The Act of Killing

A must see documentary.
I have not seen it. I only saw the trailer (I have a weak stomach for massacres) but I have heard about it in detail from a friend who saw it and I have read about the movie as well as the massacres themselves.
Humans. What a frigging species.

We did our share of killing in 1947 and then in Bengal in 1971, but the way these Indonesians have not just honored the killers (which we did too, in many cases) but openly boast about their work..that does not seem to be our way (yet).
Somehow I always have the feeling that South-East Asian societies (Burma to Indonesia) are one step ahead of mother India in the mass-killing business, but maybe I am just prejudiced. I have certainly not done the math...
