"I'm going to paraphrase Nietzsche, when you judge a work, the work judges you."
I have a theory about the little man that just occurred to me.
Buying the Superman concept came before his other appearances and his acts in Action are him manipulating his brand. Maybe Superdoom has become outdated and he's chosen this fresh version to be manipulated into a new dark anti hero. He'll then sell his brand across the multiverse as a rebooted Superdoom.
