Fresh, likable, and stylishly low-key, this wistful and sexy romantic comedy marks the feature-directing debut of conceptual artist Miranda July. There are a lot of strong performances by relative unknowns, but what really holds things together is a certain sustained pitch of feeling about loneliness. July plays a shy video artist, supporting herself as a cabdriver for the elderly, who becomes interested in a recently separated shoe clerk (John Hawkes) with two sons. The movie’s flirtatious roundelay also includes the clerk’s coworker, an art curator, and a couple of teenage girls. R, 90 min. (JR)
