Tubegazing: The Messengers

The Messengers (TLC, starts July 23, 10 p.m. EDT): TLC's search for "the next great inspirational speaker" gives fresh meaning to televangelism. "The Messengers" brings together 10 orators – ranging from a Muslim youth lecturer to a social worker – and sends them on field trips, such as spending a night with homeless people, to gain inspiration for their talks. Too many of the speakers preach hollow platitudes, but a few of them, including Robert Rutherford, a Southern minister who resembles Christopher Walken, command attention. The series holds promise, and its aspirations are worthy. Grade B+
