If you're writing about a character, if he's a powerful character, unless you give him vulnerability I don't think he'll be as interesting to the reader.
Stan LeeFrom 1940 to about 1960, I had been writing just regular comics, the way my publishers wanted me too. He didn't want me to use words of more than two syllables if I could help it. He didn't want me to waste time on worrying about good dialogue or characterization. Just give me a lot of action, lot of fight scenes.
