“McFarland, U.S.A.” is a very kind and gentle film. It doesn’t offer a single surprise, but it has feeling, courtesy of director Niki Caro, who made a name for herself with 2002’s “Whale Rider,” and then promptly lost her mojo with the muddled “North Country,” from 2005. Returning to semi-stable dramatic ground with an underdog sports movie, Caro crafts an emotional picture, aided by wonderful performances from the entire cast. “McFarland” isn’t always consistent, and shows strain in the editing department, but when it finds a cozy spot of empowerment and community generosity, it charms in a big way.
