My favorite Superman moments, I believe, are the ones where he confronts the limits of his own powers and understands that — for all his abilities — he is still a mortal being. Whether it’s the realization that he can’t stop humanity from destroying itself or getting backhanded across the solar system by some creature conjured by Lex Luthor, those are the times when Superman is at his most vulnerable and his best.
Like this one:
It’s the “Oh…my…God” that gets me.
