I don't think Black Panther will be a big hit with Trump voters however it serves a political purpose so it cannot fail. Whether it actually fails doesn't matter-the media will make it out to be a yuuuge success with number fudging if it has to.
This is the closest thing to the kind of movies that used to be made before the anti-whiteness started. I suspect Black Panther will not have any neurosis over his parents and does not need a multicultural crew like the white superheroes do--and unlike Thor (alien) Captain America (science experiment) or Tony Stark (armor dependent) BP was already a strong warrior to begin with. He's like a black Doc Savage-you know, that blonde white guy who may be portrayed by Dwayne Johnson..
