I don't remember them saying that at all, got a link? . People are speculating it will be structured like "Batman Begins" because that was the template that Goyer and Nolan used to tell Bruce's origin. I think the whole point of this is to get separation from the DonnerVerse. Not to copy it.
I didn't say they were going to do any of the Krypton stuff. I just find the idea of speing more time on them to be a waste.
Batman Begins is a good template but I don't think we need another Superman origin story or a dark mood. Superman is supposed to represenet hope, not the jaded cynicism that is all over the entertainment industry nowadays.
