I think people mistake the fact that Black Panther had alot of black culture that made it break out more than just being an all black cast from the first trailer we saw the african inspired clothing, the lip plates, African markings on the body from the skin to the designs.
Its the same reason why I chuckle whenever people really think a cyborg film is gonna breakout like Black Panther but I do think this could somewhat breakout. I'm actually surprised Sony hasn't announced a Miles movie yet for their universe and just leave Spidey to the MCU movies
