Hayden's ghost makes no sens if you did not see the PT.

We just saw Sebastian Shaw without the mask few scenes before. Even when I was 8 years old I recognized him at the end when he comes back as a ghost. In fact it was kind of gratifying for the kid I was to understand by himself that "oh, that's Vader the way he looks when he is good!" without explanations or dialogue. Now if a young man's ghost would have appeared next to OB1 and Yoda I don't know what could have been my reaction, but I guess a big WTF?

This is probably the most intolerable change for me along with CG Jabba. Much more than who shot first anyway. Well, it is understandable if you watch the whole Saga from Episode 1 to 6, I can give you that. So this raise the question of: does this fanedit acknowledge the prequels? If yes, then I guess Hayden could stay, even if I'm against this. If not, then it NEEDS to go.

I suppose you COULD say that leaving Hayden in the shot makes sense if you're thinking of this as a six-film saga and allowing the OT to acknowledge the prequels, but silverwheel's take on this (quoted by daneditor above) is actually quite smart. As he says, Old Anakin fits with what we've just seen in the movie--it fits our ROTJ context. If Anakin is allowed to regress in years, then why not Yoda or Obi-Wan? We don't see a younger version of Yoda, nor do we see Ewan McGregor's Obi-Wan. Rather, the force ghosts of these characters reflect their appearances at the time of their respective deaths. Why should Anakin be any different?
