Agreed. I hold Joker up because it's all four aspects of Marx's theory of alienation expressed through a vulnerable person in a neoliberal society that thrives on the spectacle of punishing the alienated. What happens is the obvious result of that contradiction. Even if it wasn't written by or for Marxists, there's a tremendous amount of agitation value there in asking how societal failures produce the monsters that attack us. The superhero side of it is forgettable enough that there wasn't one in that film and it didn't feel missing.
