I dont understand whats so bad about the sample you posted.
It’s the same make-up/mask used in RotS, which is much different than the RotJ look.
I get that anal retentive fans like that it’s the same actor, but the execution is awful. As are the stupid changes to the dialog in the scene.
I personally love the original Emperor & wish they’d stuck closer to that. Clive Revel’s voice is awesome & the look is creepy & mysterious.
I dig Ian too, though. (In Jedi. He’s silly in everything else.)
