A nicely subtle parsing of the stereotypes of African-Americans that have dominated popular culture in America since the early days of slavery. The commentary on the evolution of types, and the cultural motivations for the creation of caricatures like the laughing Sambo or the asexual Mammy, is particularly interesting. Both an invaluable historical documentary and an insightful commentary on the larger impact of racist, harmful depictions in popular culture on the people they're intended to ridicule and belittle. Derisory caricatures of blacks have both inspired and justified (and helped to make legal) racism and racial violence.
