I feel like the premise could be done well, grappling with the idea of Great Men even under a socialist system and the issue of someone fundamentally from outside the people trying to come in and reform things and help them, but I don't feel like Red Son does it because of the fundamental edgy liberal perspective of its authors. Like Superman's micromanaging and insistence on handling everything himself was flawed, but its refutation should have come from within the socialist context and not from a single pithy remark from Lex Luthor, and it certainly shouldn't have been a hamfisted allegory for socialist policies in general. The closest thing is Batman's attack on him, but there he's just being a violent wrecker out of an extremely personal vendetta and thus fundamentally cannot refute Superman's approach.
