If you truly feel the O-OT is perfect, then that's your view and there's nothing wrong with feeling that way. It is because taste is subjective that I am for maintaining the original versions almost as much as the rest of you are. Sure I would still get by with the newer updated versions and be happy enough, but I truly want to see the fan base together again. To have everyone rise above their own personal points of views to see the multitudes of other views out there and to be able to accept and appreciate all of them for representing the unique points of view each one of us has to offer.... From a certain point of view (somebody stop me! 
)
I think it would be a whole lot easier to get to that point if the fans who prefer the originals had their favorite movies too. If you guys can be happy about things, it wouldn't be so hard to get along with the fans who love the new ones too I think. I keep talking about the anger I see here towards Lucas, and I think it really isn't about hating his point of view as much as you hate feeling left out in the cold by the very franchise you loved the most in the first place. I got upset when I saw someone say "Lucas talks crap in Variety, would sell his dead cat for $5". But now I realize that it's more of a running joke to put Lucas down in as sarcastic a way as possible than some kind of actual hate towards Lucas.
To me the whole saga is greater than the sum of it's parts. I think Mark Hammil was a bit hammy in places, Carrie Fisher's acting was hit and miss, Harrison Ford's acting doesn't seem as good to me in ROTJ. There are technical errors (artifacts from the special effects), continuity errors, convenient plot points (Lucas to all the characters: Come on who wants to be related to Luke next?).
To tell you the truth, I felt that before the prequels, Leia being Luke's sister was a cringe worthy way to tie things up in ROTJ. Watching Vader suddenly pull his goodness out of his ass at the last moment made good narrative sense, but I felt it was a bit thin. You know like "oh Darth's good again and we can all go home now".
With the prequels, I feel Leia being Luke's sister has a lot more to rest on than it did before, which sort of legitimized that development in ROTJ for me. In the same way, seeing who Anakin was before he became Vader has made his return to the light side one of my very favorite moments in the whole saga.
As I look at this as a whole saga, for me it makes better sense to have Hayden in as the Force ghost, because to me that says it's the good part of Anakin that had remained, and not that part of him that had become the twisted wreck of a man known as "Darth Vader". Sure Shaw was the face he saved Luke with, but to me it just visually represented what he had become more than it represented what he used to be.
You say he didn't -have- to put Hayden in there and you are right. But then again Lucas didn't have to make Star Wars in the first place if you get right down to it. Originally posted by: Gaffer Tape
Yeah, I agree with canofhumdingers's interpretation of the scene. It makes Vader willfully evil to follow the Emperor. It just doesn't make any logistical sense to follow him for an entire generation if all he's really doing is waiting for a chance to overthrow him because he doesn't like what he's done with his life. If he was that unhappy with his decisions, he should have abandoned the Empire or simply killed himself. Anakin became Vader because he was at a point where he felt the Jedi and the Sith were both just as bad in this whole mess. He never denies the evil of the Sith, he merely says that from his point of view the Jedi are evil. Then he talks to Padme about how he's going to overthrow the Emperor. To Anakin the ends justify the means. To him what he is doing is ultimately for the greater good of the galaxy. After Padme dies, his all-consuming passion is to control the galaxy himself so he can make it "the way he wants it to be". He has entirely convinced himself that it's a good thing he's doing. So even as he is being evil, he never makes one of those evil laughs of someone who relishes being evil (as the Emperor does), his tone is one of self-righteousness. As for killing himself, that's just not in his character to let things go. He couldn’t let go of his mother, he couldn't let go of Padme, he certainly wasn't going to let go of his self-proclaimed crusade.Originally posted by: Gaffer Tape
And the new scene makes no sense because, as others have pointed out, Vader knew about Luke. He made it no secret that he knew about Luke. The Emperor wasn't calling up Vader to say, "Oh, yeah, by the way, your son is alive." That's common knowledge. Vader wasn't exactly discrete about this information, so it seems unlikely he was trying to keep his search for Skywalker a secret. The point of the call was to inform Vader of the increasing threat. Yeah, Luke destroyed the Death Star. Yeah, he's a key figure in the Rebellion. The Empire needs to get its revenge against him. But now Luke is becoming stronger in the Force. That's the great disturbance. He is becoming a threat, not just to the Empire at large, but to them personally, and to the Sith. He was about to get additional training. That's the purpose of the call. Not to establish family ties or to waste time with some very obvious (to them) family connection. That's just a silly way to (re)interpret the scene, and it's obvious George wasn't thinking too hard when he re-wrote the dialogue, otherwise he would have realized that it doesn't make sense.
In ANH Vader senses Luke in the trenches of the Death Star. In his quest to find out who was strong in the Force within the Rebellion, word got around that Skywalker was the name of the rebel who destroyed the Death Star. Vader was out in the field with first hand access to this information and yet it's a newsworthy piece of information the Emperor thinks he's giving Vader. It's not like Vader found out the name was Skywalker and he started blabbing about it, the imperial officers came upon that information and whether Vader talked about it or not it was going to get to the Emperor eventually. The title crawl for ESB talks about Vader's obsession with finding Skywalker. As soon as he found out the name Skywalker was involved, he knew it was potentially his own offspring, and that gave him renewed hope in being able to finally overthrow the Emperor.
But when the Emperor calls him up and says: "The guy we are looking for is the offspring of Anakin Skywalker" Vader can't just say: "Yeah, I know, um didn't you get my text message about that?"
He plays dumb so as not to raise suspicion about his loyalty.
To me this makes perfect sense. And it seems to be the dynamic that was already there in the classic trilogy to begin with (once Lucas settled on making Anakin Luke's father of course). Vader told Luke about how they could join forces and end this destructive conflict. When Luke wouldn't join him, he saw him as he saw Obi-Wan. If Luke wasn't with Vader, then he was his enemy. After Palpatine tells Luke to strike Vader down and take his place, it suddenly all clicks for Anakin. Suddenly he remembers how he was in Luke's position back when he decided to kill DooKu. He see's Luke's example of self sacrafice in the name of what was right, and his compassion was re-ignighted. It was at this point that he realized that what he had been doing was extremely selfish, and it's at this point he is able to let go of his sense of self and do what's right for his son and by extension the rest of the galaxy at large.
I don't know how many of you have played the Episode III video game, it isn't the best, but it's the best depiction of lightsaver combat I've seen so far. The duel sequences are really a lot of fun. Anyway, if you beat the game (spoilers I guess) you get to play the final duel again as Anakin, and if you win, they show a cinematic where Anakin manages to fly over Obi-Wan high enough that he doesn't take his limbs off and immediately stabs Obi-Wan in the back as he lands, making Kenobi fall down the lava beach to perish.
He leaves him there and goes up to greet the Emperor who was just landing in his shuttle. The Emperor gives Vader his lightsaber that he uses in the classic trilogy, and after accepting it, he immediately kills the Emperor with it, and the troopers all freak out for a second until he announces that it is now his Empire.
Sure it's just a game, but I think that plays true to Anakin's character as portrayed in the prequels. It's not that he's a good guy when he kills the Emperor in this alternate sequence, he's just taking control like Palpatine did before him.
