I personally think that replacing the Emperor was one of the most needed changes.
Even Though Replacing the emperor in ESB-2004 does add a bit of well needed continuity, the emperor still doesnt look very much
like the ROTJ version. Plus they have changed some of the dialogue which was'nt needed and removes tension from the climax with
the Vader/Luke Fight at the end of the film.
Ive always liked that weird woman with the superimposed monkey eyes for some reason. Ha
