I don't necessarily hate it I think it's too soon to tell but I will say that Onyebuchi's writing seems better in his Cap book than in Legends. Then again Legends is directed towards a younger audience.
His line at the end of issue #2 could be implying that he's behind what's going on in Wakanda and as a BP villain/supporting character I do think T'Challa is bound to make an appearance at some point.
