Now that I've seen it... It's not the best MCU offer [spoilers]
Good MCU movie? sure.
The best? No.
CGI was wonky at places. Not as bad as WW's or Justice League's level of bad but still very noticeable and - on the train sequence - quite cartoon-ish [or video game like, whatever you prefer].
The sequence of the Throne possession was somewhat off putting in regards to visuals. Couldn't help but notice the "copy-paste" rendering of the people on the side of the mountain. And so was the Dream sequence near the end. Green screen is very noticeable.
The last sequence has STAR WARS written all over it [ships fighting and sound]
"Colonizer" [this one cracked me up, specially because of the irony] and "another white boy" levels of racism. Oh goody.
"2 billion of our kind so.. we black we need to stick together and kill the white devils in power, dawgs, cause da blacks gott no weapons for revolution" level of xenophobia. Marvelous.
Wakanda [formerly a self serving Nation that couldn't give a rats ass about other African nations, aparently] now is going to extend their "assistance" to the outside world. Cool. Let's hope it's not for blacks only [the end credit scene features black people prominently at the UN - the camera centers itself on them in the audience; also, the "hood" where the kids are playing - black kids - yes, it's where BP's uncle was killed, but the vibe is "hood"] given Killmongers' message.
The cast was pretty good. Don't think Killmonger is the best MCU villain at all. Zemo still wears that crown for me when it comes to "a normal guy with a vendetta that stands against the hero" type. Don't care for Loki in the slightest either.
There are beautifully crafted scenes throughout the movie.
The last action sequence is the best one in the entire movie.
"guns.... so primitive... let me throw at spear at them"
"WHAT ARE THOSE??!!!"
"I neva freeze... Did he freeze? yeah"
M'Baku [Man Ape] was great. I prefer him to Killmonger.
EDIT: It's a rather heavy handed movie with the obvious "we black" message and directed at the black American community. As a movie by itself, has its moments but it has pacing problems.
