I might be in the minority but I don't really give a shit about Black Panther in Civil War. I really don't. In fact they really need to focus on all that in the BP movie.
Tell the story of why Iron Man and Cap are fighting and then show them fighting. Its that simple. What the fuck does Wakanda have to do with any of that? BP is not American so the Registration Act didnt really apply to him.
Make a good movie, don't try to overly link it with the next series.
Oh Im expecting Cap to die as well, its only logical from the comics perspective. I also want Daredevil in the movie too but I guess Im asking for too much.
