I am not a fan of superhero movies. From what I’ve seen, most of the mainstream superhero genre is orientalist, racist, misogynist, and profoundly white (Dr Strange is an obvious example here, on a number of levels). It seems that a modern superhero is not required to fight the forces of state, systematic oppression — particularly if that is race-based oppression.
Instead, for the large part, action superheroes tend to be portrayed literally as white saviours against external (often racialised) malevolent forces. In the case of Suicide Squad, the external menace was literally a powerful dark spirit of pre-European America (which the US government were trying to violently control).
