This is a brilliant summary of the Nolanman trilogy. Goyer and Nolan were so slavishly devoted to "realism" in a series of superhero movies that they robbed Bruce Wayne of his singular drive and devotion. The idea that a boy would dedicate his life to "war on all crime" is ridiculous to them, yet that's the core of Batman's character. Grant Morrison said in an interview with Kevin Smith years ago that Bruce Wayne's reaction to the loss of his parents seems "unrealistic" and even silly to an adult, but perfectly reasonable and achievable to a child. It's not a childish concept, but instead, a childlike concept. This is why Bruce Wayne is so unique. Most people would either become self-destructive or destructive to others in light of tragedy, but he used his trauma constructively. Frank Miller and other later takes fail to see that Bruce Wayne is not "insane," but, as Morrison also said, "super sane."
As for Superman II, that's all we see happen to the PZ criminals. They fall into fog, which somehow is the same as dying to people that desperately need their superheroes to kill. I'm not sure what it says about people that defend Superman killing from the perspective of "I can't relate to a hero if he doesn't kill!," but I know it's not good.
