This is a racist show. And when i say that, i'm not even talking about the depiction of the black woman Sister Krone.
In the first episode, they introduced a brown/black kid, and i was immediately curious how they would depict him. Soon, after a test, these three white kids are revealed as "geniuses", immediately following which, the brown/black kid is immediately shown saying something stupid and everyone laughs at him for "weak judgement/losing his cool".
A few scenes later, we get yet another scene where a bunch of white kids point at the same brown/black kid and say "Look, he's losing his cool again".
I've read elsewhere that the other black character i.e. Sister Krone is depicted in a very racist manner. I've seen a few images of that character, and i'm not the least bit surprised after what i saw in the first few minutes of the first episode.
