Alongside Dope and Me and Earl and the Dying Girl, Diary of a Teenage Girl was one of of a trio of coming-of-age films that left audiences enraptured at Sundance this year, with our critic Bilge Ebiri praising the “earthiness†of festival breakout Bel Powley’s performance. Set in the “liberated†world of ‘70s San Francisco, the film stars Powley as a teen girl who falls into a romance with her mother’s boyfriend (Alexander Skarsgård). It’s creepy, but as this trailer makes clear, it’s also kind of cute.
