Easily the best family-oriented black experience movie of the early 1970s, the Third World Cinema Corporation’s first film features Diahann Carroll and James Earl Jones in a funny, endearing saga of life in the welfare system, with human feeling and compassion to spare. But the triumphant socially progressive movie fails the 2020 diversity test — its primary producer, cameraman, writers and director are white. Are we still allowed to enjoy it? With Lawrence Hilton-Jacobs, Tamu Blackwell, David Kruger, Yvette Curtis, Eric Jones and Socorro Stephens. On Blu-ray from The Criterion Collection.
