MBJ was FANTASTIC in this role. He is hands down the best MCU villain and he played it with fearful charisma. Although, I will say, and I have to watch it again to fully take it in, but I didn't sympathize with Kilmonger one bit like it seems a lot of other people have. He didn't come off as an "i feel your pain and I understand your motivations even if i dont agree with them" type of villain like...Magneto for example. Magneto is a guy I can almost get behind even if his actions are extreme becuase you genuinely feel horrible for what he's been through. I never connected with Killmonger from a sympathetic standpoint because from scene one he seemed like he didn't give an F about anyone but himself because he was so full of hate, the guy was completely heartless and I think because of that I couldn't, even a little bit, get behind his actions and his goal.
