Bob Cashill’s review published on Letterboxd :
Hot on the heels of the more evasive TRAINWRECK, an excellent, non-exploitative movie that "goes there," with naturalistic, credible (and at times cringeworthy) sex scenes. Twenty-three-year old Brit Bel Powley is terrific as Minnie, a 15-year-old in 1976 San Francisco, who chronicles her sexual misadventures, beginning with her mother's boyfriend (Alexander Skarsgard, equally good in a difficult role.) TRAINWRECK spiritual mother Kristen Wiig plays Minnie's mom, who does coke with her and is otherwise not the best guide through a turbulent adolescence. First line: "I had sex today for the first time. Holy shit!"
