Palpatine as Sidious was such a badly executed plot device I was always expecting a twist of some kind to happen.

I touched on this in another thread, but they missed an opportunity by introducing Sidious in TPM. Instead have a villain with no clear ties to the OT, get people invested in the present plot instead of waiting for some reveal, and only in the final movie does it become relevant that "PALPATINE'S BEHIND IT ALL".

Also, how do you think it went when Palpatine got into his "Sith" persona? Do you think maybe his valet or whatever walked in on him making one of those "Kill the Jedi" holograms and he had to make up a story on the spot about some kind of historical reenactment society? Or did he just throw on the robes on his way out the door and say "Jeeves, I'm going for a night on the town"?
