Directed by no other than Roman Polanski, ‘Carnage’ is a razor sharp, biting comedy centered on parental differences. After two boys duke it out on a playground, the parents of the “victim” invite the parents of the “bully” over to work out their issues. A polite discussion of childrearing soon escalates into verbal warfare, with all four parents revealing their true colors. None of them will escape the carnage. The film start Kate Winslet and Jodie Foster, among others.
