The Good:
-Hayden as Anakin’s ghost. It doesn’t make sense for him to appear as an unscarred Shaw because he never looked like that.And yet you think it makes sense for him to appear in the Jedi robes that he never wore? And how the hell would Luke even recognise him. It makes more sense for him to be Shaw than it does Hayden.
If Shaw is used, this is the only version Luke would recognize:
Finally someone who gets it! That said, Adywan’s right about Luke probably being able to recognise him unscarred. My point is just that I don’t see why he would appear that way in the first place.
