(30% of the reason I watched Black Panther was so I could jump into these discussions, kukukuku.)
Fencers is right, the whole motivation of the villain was to arm BLACK people around the world with weapons to fight their oppressors. This is as opposed to what BP's girlfriend wanted, which was to assist other countries by offering them tech/weapons/medicine..
But it's not like the villain did that because the movie was about black people, it's because he grew up in the ghetto, his dad was sent out of paradise into the real world, and was killed by his brother (without a funeral or anything) because his dad was trying to help oppressed black people (which was legit in that time period even moreso than today). Then the villain went around the world seeing oppression when he was in the military.
And it was actually true that Wakanda was living like a city of gold while everyone else suffered. Wakanda happened to be the nation where vibranium was literally limitless, and all the other black people had to migrate and be sold as slaves just because they were born a bit further away. Totally not fair.
That's why when I read other people's reviews, I completely agreed with them saying the villain was amazing. It's not just that he was charismatic and not evil4evil, but his cause and reasoning was 100% legit.
But I don't think all that is because the movie is black, it just happens to be what the villain (and heroes) backgrounds were. No one complains about spiderman being a science nerd every origin story he goes through. It's just the character.
I'm pretty consistent. Plot, story, [comedy, action, adventure, seriousness]* originality, predictable, any overused themes, believability, and movie flaws are generally what I use to decide a movie's rating.
*Brackets are depending on what the movie is going for. I'm not gonna penalize Interstellar because there are no gunfight scenes or car chases.
Maybe I will.
