Until now, whether they hail from the DC or Marvel cinematic universes, big-screen superheroes have traditionally been white dudes put on this earth (e.g. Superman and Thor, who each came from other planets) or fashioned by the U.S. military (à la Captain America and War Machine) to defend America from its enemies. Co-written and directed by Ryan Coogler, Black Panther is a radically different kind of comic-book movie, one with a proud Afrocentric twist, featuring a nearly all-black cast, that largely ignores the United States and focuses instead on the fictional nation of Wakanda and guess what: Virtually everything that distinguishes Black Panther from past Marvel pics works to this standalone entrys advantage.

If it turns out to be a good movie in the eyes of comic fans, great, I'll be just as happy with it doing well as I will be with it doing poorly. Macht nichts.
Any way it goes it doesn't reflect any change in the sewer it comes out of.
