I try to ignore all the retconning, PT, EU and so on, but I have to say...I can't look at Vader the same way anymore. Part of it is I've obviously outgrown the character, but he went from a mysterious villain with a dark past to a misguided emo kid in a cape. To my taste that image of him with Threepio's head is laughable and pathetic.
My low opinion of some of these creative decisions isn't restricted to the PT. I don't buy the "redemption" garbage from ROTJ. His character was a genocidal murderer.
There is no coming back from what he did. That truth would have made the Dark Side truly dark and frightening (if destroying entire populated planets wasn't dark enough already).
Don't worry, I get that elements of these stories are not to be taken too seriously, so I won't lose sleep over it.
OMG lightsabers!!1!
