I agree, I think Krypton with all its various interpretations depicted as different clans or historical eras of Krypton, makes it feel more like a real planet than anything else in sci-fi in terms of diversity. And I love that each new version of Krypton adds to it. The specifics of Jor-El & Lara may change over and over again, but what they represented gets rolled into Krypton's fabric.
