I had no problem with that part of Byrne--it was throwing out so much of the "silly" stuff(which they've been restoring ever since) I had a problem with.
And this is what Tarantino gets wrong in KILL BILL. Superman COULD have been that, it's true. But he had these parents, and so he does think of himself as Clark. And thank god for that. Imagine otherwise. This Clark--really, it's just lack of imagination that kept him from being a monster. He was, by the 70s, alien and remote, and much like Chris Ware's "Super-Man," who's like a malevolent, capricious God.
