War Machine follows the story of one American general in a line of many, who were assigned to clear the war in Afghanistan and ends up as collateral victim in a more insidious kind of war, waged on the trenches of the bureaucratic army chains of command. Brad Pitt offers a good crafted character, keeping the film upbeat and comical, thus steering away from any moralising subtext. Because it’s all out there, unpretentious and simple: Americans don’t know what they’re doing.
