By Lucas changing scenes he actually made a fan of the movies pick sides: Do you like the new Hayden or the old Sebastian Shaw in ROTJ? Do you like Greedo shooting first or Han shooting first? By doing that, he created two fanbases cause it is IMPOSSIBLE for someone to like both! If Lucas redid some of the battle on Deathstar like the X-Wings leaving Yavin, or ObiWans new Hutt, or even the new Jawa Sandcrawler, that stuff is not jarring, and really doesn't change the movies one bit, a NEW ACTOR in the force ghost scene does!
The bottom line for me is Lucas went too far in changes, and actually turned a fan like myself, who grew up with the OOT, a person that could have liked the SE if were just subtle changes, to a hardcore OOT fan now because I just put my hands up. Lucas like the Emperor got greedy with the OT movies.
