Coogler still has some ways to go, but he is on the right part. Not much to completely tell from his Black Panther movie because MCU makes their movies very manufactured, however if we were just to judge him on Creed and Judas and the Black Messiah, yeah, I see him getting to the level Steve Mcqueen.
Usually when it comes African American actors or directors or entertainers , I hate using the term the ''next Denzel Washington'' or the ''next Spike Lee'' to describe a newcomer, because it feels more like trying to put two black entertainers against each other or using them to replace the other, which itself is racist, I know this well from watching documentaries about Naomi Campbell and Tyra Banks and history having a rule, that they only allow....one black person at a time to shine.
