People love to harp on the changes Lucas made to those, but honestly - other than Greedo shooting first, Vader's stupid "NOOOOOOOOO!" in Jedi and sticking Christensen's creepy rapist-glare ghost in - I dig them.
EDIT: OK, I forgot about him re-dubbing Boba Fett too. Although I don't think that would bother me either if Temuera Morrison's delivery wasn't so painfully flat.
