I believe removing Palpatine entirely from the film would be either impossible, or the amount of excision needed would leave the film unsatisfying.
He doesn’t have that many scenes, and you could have Kylo do all the legwork since he pretty much already does.
Regardless, I prefer having Palpatine. In fact, I’m extremely thankful he’s there. The story just wouldn’t have felt like a meaningful part of the Saga without him.
As for editing the Originals, I have no restraint. Nothing is sacred here. I hold all the films to equal scrutiny. What I value is a cohesive nine film saga.
