I missed this one when it was at the cinema, but I aim to watch all the films that won the "Best Picture" Oscar.
It starts with the quote
"The rush of battle is often a potent and lethal addiction, for war is a drug."
And the whole film is basically an illustration of that.
It follows the story of a bomb-disposal team in Iraq towards the end of their time there, with all sorts of hard-hitting encounters between them and Iraqis.
I wouldn't say it was a pleasant film, or a nice film to watch. It isn't something I'd especially like to watch on an evening in front of the TV. But it's a really good film, and a thought-provoking one.
