Its actually an origin story lite for him with lots of cameos from wakanda.
so pleased he nailed an accent too its essentially a perfect generic "african from africa town voice" and not jarring like idris in beasts or will in concussion
And stick around for the post post credits scene for more black panther

Overall it feels like avengers assemble x winter soldier in that it handles the vast cast as well as the former and is close to being as tight as the latter as to be a good movie.
I think I still prefer the tightness of winter soldier but cant wait to see this again
