Tiny Furniture may be the most adorable movie ever made about people who can’t be bothered to recognize your existence. It’s a fairly typical liberal-arts-graduate-returning-home-after-college-to-figure-things-out movie. Only home is a gorgeous, two-story Tribeca flat where mom and sister (director Lena Dunham’s real-life mother and sister) live the privileged life of, well, people who live in a gorgeous, two-story Tribeca flat. Dunham merely sorts things out, feeling like a visitor in the apartment -- and city -- where she grew up. Dunham captures this life with an insider’s beguiling eye. If Tiny Furniture feels a little coy, remember that it is a post-collegiate finding-myself flick. Costar Jemima Kirke steals every scene she’s in. Her Charlotte embodies the sort of indolent downtown decadence that’s been drawing young people to Manhattan for generations.
