We watched The Great Debaters on DVD recently. True story of the Wiley College debate team invited to Cambridge where they took on Harvard's team in the early part of last century. Quite a wonderful story with Denzel Washington as the coach, and other actors you'll recognize. If you saw Precious, The Great Debaters (along with many other recent excellent films having Black themes), would be a good antidote.

From Armond White's review of Precious: "...Perry and Winfrey naively treat Precious' exhibition of ghetto tragedy and female disempowerment as if it were raw truth. It helps contrast and highlight their achievements as black American paradigms--self-respect be damned."
Mr. White provides a list of movies with Black themes.
