In an interview with Empire Magazine, J.J. Abrams talked about his failed superman script and the unique approach he took to the Superman character.
The thing that I tried to emphasize in the story was that if the Kents found this boy, Kal-El, who had the power that he did, he would have most likely killed them both in short order. And the idea that these parents would see –- if they were lucky to survive long enough –- that they had to immediately begin teaching this kid to limit himself and to not be so fast, not be so strong, not be so powerful.
The result of that, psychologically, would be fear of oneself, self-doubt and being ashamed of what you were capable of. Extrapolating that to adulthood became a fascinating psychological profile of someone who was not pretending to be Clark Kent, but who was Clark Kent. Who had become that kind of a character who is not able or willing to accept who he was and what his destiny was.
The idea in the movie was that he became Superman because he realized he had to finally own his strength and what he’d always been. I don’t know if that’s what Zack and Chris [Nolan] are doing, but it looks like that’s part of the idea and I could not be more thrilled to see that movie. That to me was always the way to go.
His script was on the death and rebirth of Superman and featured a new Kryptonian villain, Ty-Zor. Those details don't seem to be in the Man of Steel movie, but the theme of examining his powers and how best to use them may. As for this reporter, as big a fan I am of Abrams, I can't say I'm in love with what I've seen here past the rough theme, and AICN wasn't too fond of his work either.
