Thai export Mary Is Happy, Mary Is Happy is an all-around goddamned great movie. Loosely adapted from 410 consecutive tweets written by a real teenage girl, Happy coalesces into an episodic structure, with sudden bursts of bizarre violence, occasional absurdist digressions, and a sophisticated sense of melancholy. Mary’s banal observations—one minute she tweets, “104.5 Love Radio is pretty good,” the next she despairs, “The truth is maybe I’ve got nothing”—are published on the screen as Mary struggles with love, putting together a yearbook, and the wide-open expanse of future staring her down.
