I have no problem with the special effects being cleaned up and subtle stuff like, cloud city being shown outside the windows and x wings approaching the death star, establishing shots flying in to cloud city or some tentacles on the sarlaac pit. That stuff doesn't mess with the narrative
But shit like dialogue changes, voice actor changes, new dance numbers, character removals, character additions, ie Hayden ghost and stuff like Vader going "no, no" in return of the jedi. Fuck all of that.
I'm honestly surprised that lucas didn't add in extra dialogue when vader was in his meditation chamber of him saying "i miss padme, i miss padme..."
