The First
That was fine for the first set of movies. Everything was new, nobody really had a heavy backstoryPalpatine never got a back story. And if you mention one damn book.
But now we have six movies where a whole saga was set up, and the heroes overcame great powerful enemies to save the whole galaxy. And now you have this new dude that was able to just negate all of that, with no explanation of how or where he even came from before you killed him??
