I personally love the original Emperor & wish they’d stuck closer to that. Clive Revel’s voice is awesome & the look is creepy & mysterious.
This 110%.
I dig Ian too, though. (In Jedi. He’s silly in everything else.)
He’s silly in ROTS once he whips out his laser dildo and goes full Henrietta. Before that point, he’s very good; I’ll go so far to say he’s better in most of the PT than he is throughout ROTJ.
