Thats why I think Superman is such a lame superhero. Plots revolving around Superman (and arguably Flash) only work when they conveniently forget they have superpowers.
I mean, Superman has an X-ray vision which goes through everything else but lead. He can cause new Big Bangs by punching space. He's basically omnipotent and the only two weaknesses he has is that he's not very smart and green rocks make him puke.
