P.O.V. on PBS

This acclaimed, long-running documentary series is a showcase for independent films on a wide variety of subjects, from the heartwarming (`Sweet Old Song,' about a 91-year-old musician) to the whimsical (`The Sweetest Sound,' a study of names) to the controversial (`Live Free or Die,' about an abortion doctor). Whatever the subject, the most important criterion is that the films express a `point of view.'
