Marielle Heller’s The Diary of a Teenage Girl is astonishing in its audacity. It gives agency to its 15-year-old female protagonist Minnie (Bel Powley) when she has an affair with a man who’s 20 years her senior and also her mother’s boyfriend, Monroe (Alexander Skarsgård), and then it dares you to contemplate her level of victimhood. It portrays the sex between Minnie and Monroe as enjoyable and hot. It finds humor in a fucked-up situation that might be portrayed as a tragedy in a less compassionate movie: One of the times Monroe announces he has to stop fucking her, Minnie gasps in offense, “Why would you say that? Do you think I’m fat?”
