“Clementine” follows Karen, who's in her twenties and fresh off a break up with an older woman. She holes up in her ex's lake house, where she meets Lana, a precocious teenage girl. The two form a strange bond, with each seeking some sort of validation from the other. The movie speaks most poignantly in moments with little to no dialogue, and the lush backdrop only enhances the story's sense of being adrift. — Brit Blalock
