Demetri Martin makes his directorial debut with Dean, a spiritual descendent of Wes Anderson and mumblecore rom-coms that sways gamely between tentative and confident before ultimately settling on a sort of quirky but lovely sincerity. Kevin Klein and Mary Steenburgen burnish their reputations as national treasures, giving it with both barrels apiece, and Briga Heelan steals her every scene as a The Girl You Wish You Hadn’t Started a Conversation With at a Party. Martin makes a winning leading man as much by letting his costars shine as by his own self-deprecating hipster charm.
