The history of television and film portrayals of people of color is pretty abysmal. Either we are not present, just in the background and stereotyped, or we're cast as maids, gardeners, servants or the comic buffoon. In my lifetime, I have never been exposed consistently to characters who either look like me, act like me or reflect my reality of those around me.
Notice I said consistently. There have been exceptions, but it seems we've had to wait patiently for portrayals that we recognize as being significant to our lives.
