Just heard this, absolutely horrible. Black Panther was a total banger of a film and he absolutely nailed the character.
I hope they're still do the 2nd Black Panther film, I'm sure CB would have wanted the series to carry on.
We appear to have found an odd corner of the Internet where more people dislike Black Panther than like it....! I haven't seen much of his other stuff, but Avengers Infinity War and Endgame are so good it's unreal.
