Just saw it a second time today, Damm I ended up enjoying it even more than the first time. Perhaps, it is my second favorite MCU film just behind The Winter Soldier.
The secondary characters are amazing, Wakanda is so credible!! Like I wish it existed, the soundtrack is like the best one out of all Marvel movies, Killmonger is one of the best supervillians of inside this universe, the story is interesting and with meaning.
Just pure fun overall, the only two problems to me were the CGI in some parts (that last T'challa vs Killmonger fight, the second astral plane, those CGIs Rhinos and some acrobatics made by Black Panther that were so unnecessary to make them full CGI instead of using a real stunt person) and Killmonger needed more screentime.
