I disagree but after all that is my opinion.
Anakin/Vader was done in such a way in return of the jedi to make the audience sympathetic to the character. Not so Hayden Vader who never was a good man or good friend to begin with. He was always a traitorous asshole from episode II onward to III. I have to therefore fly in the face of Lucas continuity and disavow the existence of the prequels because they ruin the original trilogy.
