The best Canadian documentary since Surviving Progress, this Sundance 2012 selection is based on the book by Margaret Atwood, whose deadpan lecture of excerpts from it acts as narration. Exploring various facets of debt, be it financial, political, social, moral or ecological, Payback is thoroughly thought-provoking in the way it draws parallels between things like the treatment of migrant farm workers in Florida, a blood feud between two Albanian families and the BP oil spill. Meanwhile, Jennifer Baichwal mixes talking-head segments with striking, evocative visuals accompanied by a great ambient score by Martin Tielli and Gabriel Morley.
