At this point, with all the damage done by Coates to the BP mythos, most of us are just interested in another writer with a positive non-cynical outlook writing the Black Panther comic.
Based on this interview with Evan Narcisse (
https://io9.gizmodo.com/ta-nehisi-co...her-1786632598 ) Coates is somewhat aware of the problems fans of BP have with his run. We've basically been saying the same complaints the whole time ( i.e. T'Challa's incompetence, Evil Wakanda, negative African stereotypes, negative black Male stereotypes etc).
Hopefully, they will do to Black Panther like marvel did with Captain Marvel and give T'Challa a new creative team.
Coates didn't have to be a long term fan to write the character of T'Challa & Wakanda. He just had to show the mythos respect, like Priest, Hudlin & Hudlin. Something he couldn't do for 4 yrs.
