This is a slightly weird and not so slightly quirky movie to be avoided by anyone with a low tolerance to the weird or quirky. Greta Gerwig (Lady Bird, Frances Ha) and Noah Baumbach (The Squid and the Whale, also Frances Ha) write the story, while Gerwig plays a lead role. Two girls, one a New Yorker and the other having just arrived in New York for a writing program, get in touch because their parents will marry. The writer is fascinated by the personality of the New Yorker and follows her everywhere to understand her more, and eventually write about her. Mistress America is their journey through friendship and through New York. Stick around the first 40 minutes or so, because the second half of this 82-minute movie is hilarious.
