The problem is why does it need to be KAL EL when it could be CAL-El Clark Kent in black face is wack Black Version of the Alien story is interesting Whille Martha and John still be white? Lois Lane? Just blackwashing is meh There is a starvation of characters of colors. . .and that does not mean just painting characters ethnic esp major characters Rocket River
let's make all characters blek or mexican. wouldn't mind a biopic of george washington played by denzel. or sam houston (kal penn) vs santa anna (john cho) for more inclusivity.
Probably more than that, honestly, and the point remains. Society is simply obsessed with these things.
