I think kids love superheroes, and the more you can crowd into a story, the more excited they get.
Stan LeeWhat did Doctor Doom really want? He wanted to rule the world. Now, think about this. You could walk across the street against a traffic light and get a summons for jaywalking, but you could walk up to a police officer and say "I want to rule the world," and there's nothing he can do about it, that is not a crime. Anybody can want to rule the world. So, even though he was the Fantastic Four's greatest menace, in my mind, he was never a criminal!
Stan LeeIn a sense, the artwork is the most important thing in getting somebody to buy a book. The person probably won't buy a book if he doesn't like the artwork. Once you buy it for the artwork, you hope that the story will also be good.
