This movie is underrated for real. Like, people talk shit about the CGI but through the majority of the film, it's amazing. That sand effect and the beginning and end is mesmerizingly good.
Killmonger is great every scene he's in. I always hated him from the comics but he's one of my favorite film antagonists of all time.
A lot of people don't get it because it's so outside the perspective they are used to; which makes it that much better, really. There are very few mainstream films that aren't specifically written to please white males ages 14-35(even if you're not this, this is what you're likely used to) and it leads to people calling the film overrated because they don't "get it". They talk about the third act's CGI because they can't identify with the characters for reasons that says more about them than it does the film.
Props to Ryan Coogler, Joe Robert Cole and Kevin Feige for making this flick and it's deserving success. It really is a special picture.
