The TVI Take

Marielle Heller's 2015 directorial debut, adapted from Phoebe Gloeckner's graphic novel. Bel Powley plays a fifteen-year-old in 1976 San Francisco navigating an affair with her mother's boyfriend.

Heller treats teenage female desire as a documentable subject rather than a moral problem, animating Gloeckner's drawings into the narrative.
