Black Panther isn't about just, because he's a Black character. The villain has motives that are about Africa's relations with the western world from colonial times, and how Africans and black Americans have been treated, and the community he was raised in.

He's an interesting villain, a lot of people are quick to just say, HE WAS RIGHT instead of just saying, he has a real motivation and that T'Challa and T'Chaka, and Wakanda itself not intervening could be considered unethical because they have the power to intervene. These are kind of deep ethical questions overall. The movie doesn't necessarily present them perfectly always but that's what I got from it overall and it's great.

It's not just like, BLACK SUPERHERO GOOD, MUH PROGRESS.
