I personally have a problem going to see a movie that was made to appease a race, be it black or white. I have no desire to see Black Panther so that black people are represented. Just like if it were White Panther, and was to represent white people. I wouldn't want to see it.
I want to see movies to enjoy them, and not have to worry about a political agenda such as a race. White to be white or black to be black. I saw the previews for this movie, and I knew nothing about a Black Panther. I just assumed it was a marvel comic book that had a black lead and it looked good. And that works for me. But if it was intentionally created for the purpose of black (or white), then I have no desire. Because now when I watch the movie, I will sit there and try to read too much into the agenda, instead of enjoying super powers.
If Spiderman was black, then that's cool. But if Spiderman was originally white, don't go and make him black to appeal to subset of consumers. Just keep things as they were. Now, going forward, if you want to create all new characters, black, white, asian or whatever, boom! Do it. Do it because the lead is a good lead, do it because it fits. Don't do it to create an equal % just for the sake of equal percent.
I guess I am too much of a simpleton, and I just look at everyone as an equal.
