Palatine was a horrible parody in the prequels. Tolerably when played as a politician but when unmasked in Revenge of the Sith comic book cheese level bad.

I always preferred the version in Empire not the look but the voice characterization in the 1980 version.

Ian requested that he be allowed to do his own thing on Return of the Jedi because otherwise he would not do it.

Lucas initially wanted him to copy the Empire Strikes Back version of the Emperors voice.

He already became a comic book villain in Jedi but not yet a total parody.

I don't want a return of the character and we already know they have said they are not doing EU adaption so if he resurrected its just a bad ripoff of Dark Empire.
