^You're not making much sense. How big a role could Superman play in the 1/2 to 2/3 of the movie that he's a baby? Nolan's Batman movies are about Batman's adult world, a world that he actively participates in via both identities. Krypton isn't Superman's world, it's the world he came from. There's a difference. All Krypton needs to do is explode in short order, just like Thomas and Martha Wayne just need to get shot sooner rather than later. Give us a couple of brief scenes so we'll give a crap about them, and then they're gone. Krypton doesn't even need that much. We don't need to care about Krypton.
