Isn't good vs. evil usually an idea rife with conflict? And how did Nolan's success prove that some alternative approach can't work? Frankly, I think a whimsical Superman on the order of Alan Moore's Supreme (probably the best Superman stories written in my lifetime despite not technically being Superman) could make as much money as "guilt-ridden alien freak who struggles with identity in world where he is feared more than loved," which is no doubt what a pure Nolan Superman would be. Avengers succeeded without taking the Nolan approach. Different approaches can work for different types of material.
I'm up for either, so long as Supes himself feels like a version of that character that makes sense. I realize that movie producers don't have enough faith in moviegoing audiences to really roll the dice.
