So well said. I think in a lot of media--not just superhero comics--people deconstruct to the point of losing sight of what something inherently is to the point where it no longer works.
Maybe superheroes, like most symbolic things, are also deceptively simplistic. Because there really is a lot of different areas to explore with Superman or Batman or Wonderwoman. It's not a case of always showing them the same way. It's just keeping the core somewhere in your mind while you're doing it.
