> It's not reasonable to expect characters to be cast the way they are described (or the way most people picture them), or it's not reasonable to expect people to accept a re-envisioning? Asking because I'm not sure which way you were leaning there.

I'm saying it's not reasonable to expect characters to be cast the way people imagine the characters in their heads. Which may or may not be "the way they are described." I'm saying this because I think there are a million different ways people can imagine characters differently. "Tall Dark and Handsome" is a pretty classical example of something that means different things to different people. To me, this always meant a person of color, and I only learned relatively recently that to most people this means "Mediterranean".

The very idea that an audience has a consistent picture of what character's look like is necessarily wrong.

> The only thing I've found more annoying than companies burning well-loved franchises in movies / TV / video games by trying to "modernize" them with today's identity politics is those same companies blaming the audience and telling us it's OUR fault the project failed.

I think the projects that I've seen that have failed that people complain about "identity politics" for fail for the plot being bad. But there's a separate issue I see that's unrelated where people blame people of color on the projects for ruining the projects when in fact the companies are ruining the projects, and the people of color are often just a small piece of the puzzle. I think people very often over-react to this, and it often comes across as racist. Both of those things can be true. That the company is bad, and that the audience is being racist about the casting including black people that otherwise don't change anything about the way the movie watches.
