The only change that I see as justified was having Ian McDiarmid do the emperor's hologram in Empire because having the old lady made things inconsistent. Other than that, they should have just digitally remastered everything without adding/changing anything else.
I remember how mad I got when I saw the end of the Jedi DVD and say Hayden Christiansen instead of Sebastian Shaw. That totally ruined what was an emotional moment.
"Naturally the common people don't want war: Neither in Russia, nor in England, nor for that matter in Germany. That is understood. But, after all, IT IS THE LEADERS of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is TELL THEM THEY ARE BEING ATTACKED, and denounce the peacemakers for lack of patriotism and exposing the country to danger. IT WORKS THE SAME IN ANY COUNTRY." --Hermann Goering, leading Nazi party member, at the Nuremberg War Crime Trials
