PBS is showing a documentary called Behind Every Promise about the journey, over 13 years, of two African-American boys and their education. I heard about it on NPR and it sounds very good. American Promise spans 13 years as Joe Brewster and Michèle Stephenson, middle-class African-American parents in Brooklyn, N.Y., turn their cameras on their son, Idris, and his best friend, Seun, who make their way through Dalton, one of the most prestigious private schools in the country. Chronicling the boys' divergent paths from kindergarten through high school graduation, this provocative, intimate documentary presents complicated truths about America’s struggle to come of age on issues of race, class and opportunity. Winner, U.S. Documentary Special Jury Award, 2013 Sundance Film Festival. KCTS is showing it on Tuesday, Feb. 4 at 1:30 am and Wednesday, Feb. 5 at 6 am. It is also available to view online.
