I hope I'm at least partly wrong. I don't mean to come off as a right-wing "culture warrior" who complains about SJWs and the like. There just seems to be an obsession in Hollywood these days to ensure people who are visible minorities are depicted as the "good guys", while every movie villain is an old white guy.
I started noticing it when I watched the Netflix movie Bird Box. All the "bad guy" zombies were white rednecks and every "PoC" in the movie was a noble human who committed bold acts of self-sacrifice to ensure the protagonist gets through the story. Even among the main characters in protagonist's group, every white person was either turned out to be an antagonist or were of dubious moral character and the cause of problems for the group.
I'm not saying it should be the opposite. In the past, we know representation of minorities could be brutal. But it just feels like we've moved to an opposite extreme, which I don't think is any better.
