The hardest part is the whole Palpatine deform thing. We can logically say he is “unleashing” his dark side … or his “true” form in a sense. But when you watch it, I understand it does feel kind of random. I think I am kinda ok with it, but I do understand that is a bit harder to logically explain it, since originally he was getting deformed by his own lightning …
In my mind the easiest argument is that him deforming himself with his own lightning doesn’t logically make any sense either. So no matter what, you’re left with a confusing scene, but one option is stupid and the other isn’t.
