To the reviewer who said that the premise is dated because this type of racism is no longer a big issue: you need to watch the news, read the news, talk to anyone of racial minority - it absolutely does exist.
Violent oppression is a problem in many places all over the world - systematic violent oppression like is shown in the very first episode. The attitudes of the boys on the bus or the cops' fear: this happens in "First World" countries every day. And where we've evolved beyond violence, there still exists systematic oppression in many forms from micro-aggressions all the way up to human trafficking and modern-day slavery and murder.
There is a sci-fi/fantasy twist to this story, but the story it tells is not in any way dated. If you think race and color no longer exist, you're part of the problem. The point is to see it and not have it make a difference in your behaviors and attitudes toward those of a different race.
And I love the Aboriginal angle to this story as well since they need their stories told as much as everyone else. Also, Indigenous populations' stories are often told from perspectives other than their own and we need to ask for more told by the population themselves. Let networks know that just because one show doesn't work out, it's the storytelling not the subject matter that is less than.
