It was fine, I guess. Nothing really stood out as particularly bad or good, outside of a few cringe lines of dialogue and weird plot points.
The problem with talking about Black Panther is that literally the only things of substance to talk about regarding it are all external socio-cultural-political elements. i.e. what are the ethics of a film made to celebrate a fictionalized ideal of black people designed almost entirely by wealthy white people; why do so many people say "Killmonger was right" despite his being a shortsighted lunatic whose plans would lead to deaths of untold innocents; why do so many black people now look at Wakanda as a symbol of African prosperity despite being made up and what are the ramifications of that; how does black solidarity work in Africa where "black" isn't really an identity like it is in the west and is making a fictional "black" kingdom in Africa cultural appropriation (since Wakanda takes elements from regions as disparate as Ethiopia and Ghana in its art design); why is the idea of a fascistic Good King so popular with black people in America; and so on and so forth.
The problem with Black Panther is that none of these points of discussion have anything to do with the actual plot of the movie, so divorced from circa 2018 political discussions it has no more or less merit than any of the other mid-tier Marvel films.
