Dude, Ian McDiarmid’s still got it! I feel like a lot (not all) of skeptical fans will let go of their apprehension as soon as they see/hear the Emperor. The Emperor is tied to our childhoods, regardless if you are an OT kid or a PT kid, and seeing him, back from the dead, will feel scary and thrilling. I think reading leaks vs the feeling of those characters on screen will lead to different opinions.

I was sort of skeptical about them bringing back Palpatine, but hearing him talk to Kylo Ren, it feels so right to me. Hard to explain.
