Here in Korea there seems to be significantly less hype for this movie compared to the first BP. The first one was a surprisingly big hit, my students talked about the character in the same breath as Iron Man, Thor, and Spider-man, and often did the "Wakanda Forever!" thing. But lately all I've heard is some disappointment that the original Black Panther isn't in it, just a replacement who is barely in the trailer.
I think maybe other countries will be more affected by the lack of T'Challa on account of them being less in tune with the whole situation behind why the movie is what it is.
