The Black Panther is a fun romp, but it definitely has some issues. First, the good.
The action is fun, the emotions hit home, and the story isn't dirt-poor.
While the CGI gets ripped on from time to time, I thought it was solid enough for a Marvel movie. The fight scenes were relatively well-choreographed, as well. The ritual combat scenes were exciting and visually appealing. The fights in Korea were also fun to see, and while I'm not a fan of car chase scenes as a whole, I did enjoy this one. It was reminiscent of a James Bond movie.
In fact, that's another appeal, at least to me. The secret technology base and the fun action scenes were a great callback to James Bond-type movies. I do think the movie would have been complemented by giving T'Challa a similar vice as Bond's, although Marvel probably wouldn't veer down that line for the seemingly morally absolute King of Wakanda.
The story, well, it's a mixed bag. Everything seemed crammed together with major emotional keys being rushed through or somewhat ignored. The concept is fine though. A long lost relative comes to challenge the new king, wins, and shows his colors, becoming something amoral. The king comes back and takes down the usurper, realizing something about themselves/their kingdom in the process. It's tired, but not so tired it damages the movie.
This is where the issues begin to rise, though. The movie is really a movie and a half or two movies crammed into one. Wakanda has a ton of wonderful mythology, but almost none of it is explained. The movie never really explains how the Wakandans used vibranium was used to make themselves wealthy. It touches on it in some exposition, but there was much more that was just glossed over.
In addition, W'Kabi became radicalized by Killmonger much too quickly for such a pivotal relationship to flip. Some of the emotional aspects of the movie fell flat because they weren't given enough screen time.
Despite its flaws, Black Panther is a fun movie that adds to the Marvel Cinematic Universe. It should have been two movies, but I doubt this is the last we'll see of Wakanda.
