Black men being more bad ass than white men may be more positive but it still blurs into stereotyping. You want to get bold, cast Reed Richards with a Black actor. Then gypsy Doom's fellow non-white positive feelings Reed can clash with his gypsies are white feelings. Also, we have a built-in explanation of why Reed is so go-it-alone and driven. And casting Ben Grimm as a homey follows naturally. Also, part of the Torch's original character is not being very smart or at least, being very inexperienced. Making him so badass in some respects is revisionist, to no good purporse. If he's so badass, why's he hanging with his older sister?
