Just Do It (NC)

Sometimes even doing the right thing doesn't save you from being tiresome.

Emily James's docu-tribute to young British activists – among them members of Plane Stupid and Climate Camp – highlights what they'll do in defence of the environment, turning up mob-handed at power plants and blockading City banks. There's bravery, too, in going up against the rough-house tactics of the police in Copenhagen. But the political sloganeering – everything, but everything, is the fault of "the capitalists" – and the air of self-righteousness are unendearing, even if you applaud the principle.
