One of the most memorable entries to the 2015 Sundance Film Festival, The Diary of a Teenage Girl caused considerable controversy for its story about a love affair between a 15-year-old wannabe cartoonist, Minnie (Bel Powley), and her mother’s boyfriend (Alexander Skarsgård). With the narrative never straying from Minnie’s point of view, the film deals with the usual problems of adolescence against the backdrop of 1976 San Fransisco. Taking a fresh perspective that is rare for American cinema, this dramatic comedy portrays adolescent sexuality as something movingly unremarkable.
