“Stories We Tell,” November 15, 2013, home DVD. Sarah Polley (director of the fine “Away From Her”) choreographs and directs this look at her own family. Interviews and memoir readings with her father, interviews with her brothers and sisters, home movies of her late mother and her friends, and home movie-like reenactments filmed by Polley recreate and follow her effort to find out what’s what and who she is in her life. What her mother was like. But she’s a bit disingenuous when she ascribes that as her motive. It’s also to create a directorial conceit for her film as she probes into her mom’s life and peels it back slowly for the audience. It’s sometimes creepy and sometimes fascinating. In the end, I come down more on the latter side in appreciating, enjoying, and puzzling over this story, although, as an adoptive parent, there are parts of me that are very protective of the principals, even more than they are. Still, I’m very glad I saw this, if only to force me to wonder, once again, about what matters in life.
