For her third directorial effort, Sarah Polley tries on a documentary about her mother, who died when Sarah was 11. She interviews family members in an attempt to get a better picture of what made Mom tick.

But this is much more than talking heads. Each viewpoint is slightly skewed. It soon morphs into a dramatic investigative mystery, and ends up being nothing less than an examination of storytelling and truth itself.

You’ll enjoy this most if I tell you little. This is brave filmmaking, but Polley approaches her emerging material with a strong sense of personal ethics. Well done!
