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.
It makes sense for the Audience to see Hayden, it made more sense in the 80’s to see Shaw, but Shaw was Fubar with unhealed scars and bald so the Shaw with hair was just as unrecognizable.
Actually, in the SW universe, Luke knew his father was Anakin Skywalker, and after Ben told Luke that his father was a jedi and not what his uncle told him; he would have been easy to Google through the SW archives. Their technology is way beyond ours. It would have been great for in ANH when Ben gave Luke his father’s saber to also have had a hologram of Hayden for Luke to see. Would have been a great addition when Luke said, “I wish I knew him.” That would have also made it easier for Luke to identify his father’s jedi ghost at the end of the 6th film.
