The Story of Stuff with Annie Leonard. The very antithesis of the high production values of An Inconvenient Truth – black and white, super-simple graphics, relatively unvarying delivery style – but brilliant for all that.

Annie is Naomi Klein in a cool purple shirt, with a very clear message. The 20-minute presentation is just superb. The graphics, the speed and flow, the clarity of language, the constant refrain of the five pictures, the vocal range. A big fat tick in every box.

Litmus test 1 – my 81-year-old mother would nod her head “yes” the whole way through this. Litmus test 2 – my 10-year-old was appalled and ran in to school to tell her teacher.
