Maybe it's just semantics and sentimentality here (or my own inability to just get my head out of the story), but it wasn't Shaw's Anakin I saw getting ready to slaughter a bunch of defenseless children. There's no coming back from that. Whoever (Lucas, I presume) directed Christensen for that blue ghost appearance was way off the mark as well. I saw Christensen and I didn't see a changed man. I saw a sly, evilish grin. At least Shaw had that open smile on his face and actually was looking at Obi-Wan like he was finally back where he belonged. I respect what Lucas says about Anakin v. Vader and the resurrection, but I don't agree with it. It's the same thing as someone doing one terrible thing after another their entire lives and then they honestly repent on their deathbed. Does that erase everything? No, because the sum of who you are is everything you've done, good and bad. I think it's incredibly insulting to human beings everywhere to wave your hand and say, "Oh, but it's okay. He'd already become *Vader* when he did all those terrible things, it wasn't really Anakin." BULL. Unless you want to say Vader had already taken over when he slaughtered the Tuskens (including defenseless children, a pattern developing there), that theory doesn't wash. Anakin Skywalker was never a completely good person. Neither was Qui-Gon. Neither was Obi-Wan (though more and more, he's stepping out as the most heroic of the entire bunch, with the probable exception of Luke Skywalker). Lucas should have kept Shaw in because, like I said, we are the sum of our life's experiences. Take away everything that happened after Anakin got placed in that suit and it cheapens and diminishes the entire story.
