Haven't seen the subsequent eps yet, but I'd say it's well-rounded that the black guy can be the bad guy. And having had a black bully when I was a kid, I can attest that they exist. Firing the woke chick writer was the best move in the long run. All the hot shows that people are raving about are hot because they ditched the leftist LGBTQ, feminist, and forced diversity propaganda in favor of a strong narrative with characters who JUST HAPPEN TO BE minorities and women i.e. The Expanse, The Mandalorian, and WandaVision. Hell, there was an all-wahmen squad in the last episode of The Mando and I didn't even notice because Luke came back.
I would say its not well rounded if all the Black Characters are Bad. What does Black Bullies who are Jocks have to do with anything? Actually now that I think about isn't one of the Bullies White and Asian as well so a real Rainbow Coalition of Bullies lol.
Granted Luthor doesn't really seem to be a Bad Guy Per Se so its not an issue cause of that.
I would say all those shows are diverse so the question is more where do you think the line to WOKE is. The line is subjective based on what I can tell how much someone likes a show.
