I caught on to hype for this film fairly late and having seen it can definitely understand why that exists. On the other hand, I will only judge it for the movie it is as I am emotionally disconnected from all the influence is has for some people.
So, taking it for what it is, which is the only way judge a movie, I liked and enjoyed watching Black Panther. The acting/casting was right (not sure about the American though) and the story was fairly good and quite well told. The portrayal of the women was particularly excellent. Each of the women characters had their own strong imprint on the film and without that aspect the movie would have been pretty drab. They added more, IMO, than the cumulative contributions of he superhero and the villain, who in turn were also the right fit. The villain, without being great/very memorable, was a relatable character and didn't seem to be a villain for the sake of needing one. Also, the comedy bits were excellent.
On the flip side, the hype for the film has a great deal to do with the non film related factors and not so much to do with the actual film. It's nowhere near something like The Dark Knight which a masterpiece of this genre. Black Panther is a essentially a popcorn superhero film, but one of the better ones. I'd put in the category of GOTG/Deadpool as one of the few Superhero films I liked (other than Batman and the old Superman films).
