Just use some existing black characters or make new ones. Trying to appear woke by changing established characters is just sad. I hope the backlash is a bomb and loss, money talks.
Hollywood would never make a black character white or Asian and no one would support it, this is a double standard.
Oh it won't, it'll all but assuredly be the most successful DC movie several times over, possibly a contender for highest grossing film of all time. Every black person on the planet will pay to go see it in theaters several times, as will most liberals, millennials, and zoomers of every other race. If for no other reason than to own the boomers and republicans who are the most likely demographic to complain about a black Superman. Controversy sells, studios have a literal cash cow on their hands retconning iconic white characters for the ID Pol crowd.
