This is something I have kind of a difficult time articulating, but moves like this seem like such safe plays, like it's just someone in charge grabbing low hanging fruit in order to appease people that get impassioned about issues like this with the lowest risk of turning off their primary audience.
Another time I felt this was when they made Sulu gay in the latest Trek movie. Like, I'm all for gays being represented in mainstream media, but making the character gay that was previous portrayed by a gay actor seems like the absolute safest play they could have made for that situation. A braver and I think way more effective way to do this would be to make literally any other main character gay, preferably someone who is known for their machismo like Kirk or Bones. But no, there'd be too much outcry and we can't risk alienating our primary audience by doing something actually daring.
Black Panther is (to my knowledge) the first MCU movie directed by a black director, Ryan Coogler who is fantastic, but why couldn't he have directed Avengers, or Thor? Instead they gave the black man the blackest movie in the franchise. Seems like some executive grabbing low hanging fruit again.
I guess any representation for minorities and marginalized groups in mainstream creative positions is a step in the right direction, so there's no point getting too worked up about it, I just wish things like this came off as much braver steps in leveling the playing field and less like someone checking diversity checkboxes as a PR stint.
