It's a special edition.
Thankfully nice George Lucas (Harmy) in his kindness has preserved Seb Shaw in his original context.
He could start out being the old guy Luke (and we) just met but spiritually regenerate so to speak into the young man Padme knew.
Either way a full body replace would be much more respectful to Seb Shaw's memory than decapitating the poor guy and glueing Hayden's head on complete with creepy sex looks.
The real problem with the current Hayden in the SE is it makes no sense.
How does Vader learn to do this, why does he look young when the others look old?
It makes no narrative sense so it becomes a sticking plaster vainly attempting to stitch the two trilogies together.
I just wanted an explanation for Force ghosts that made some sense without being in your face.
Lucas was right not to make every Jedi vanish and appear as a ghost because Vader is clearly confused while playing footsy with Ben's bath robe.
I don't buy the Qui-Gon thing.
It comes out of nowhere very fast.
So it makes sense that Anakin is subconsciously doing that which he declared he hoped to do one day back in the PT.
He loves Padme and he loves his son (he doesn't know about Leia).
He keeps her alive after death and keeps Yoda and Ben alive to train and protect his child.
Consciously his Vader persona is so deep in the Dark side he can't see what his subconscious good self is doing.
It makes more sense to me that Anakin is mentally ill rather than out and out evil.
You can imagine a redemption for a man who murders children due to mental health issues rather than one who does it to further his career or political ambitions.
