For anyone that's interested, here's

Movies themselves can be powerful. After all, there's a section of the National Library of Congress that preserves them. Movies can be causes for celebration, or create tradition (how many Christmas movies are there?), or ignite imagination, or be strong commentary. They're just as valid as literature and television in that regard.
With that said, this is likely the first (if not the first) to really get Afro-Futurism, to really center the power of Black people, the first movie on this scale with a crew primarily of Black labor and talent, and as IronLegion said, the first Western film to really emphasize Africa as a positive.
Heck, even if we take this from Stan Lee's perspective, to paraphrase elsewhere: "he and other creators are inspired to create a fictional African black nation that is both a cultural and technological wonder, headed by a scientific genius king who fights crime and evil. He is not a sidekick. He is not comic relief. He isn't even a poor black boy from the ghetto who, through his own grit, rises to the level of poor white people. He is a king. From Africa. From a wondrous nation every bit the Ancient Greece heralded by the bigoted white people of the day as the reason for the cultural and civilized evolutionary superiority of white people over blacks.
Imagine you do all that. Imagine the racist hate mail that arrives in droves. Now imagine you live to 95 years of age to see the world not only accept it, but film it with panche and wonder and you get to watch the world love it."
It may just be a movie to you, but don't try to damper people's spirit and enthusiasm about it because "it's just a movie." Movies can be immensely influential and representative, but moreso, while there have been Black heroes in the past, no Hollywood movie has ever elevated Black culture and community to such visibility with such force before.
