Yes and no. Removing the Sith did not remove all evil in the galaxy, but it did rid the galaxy of at least one evil group that was a threat to the galaxy. On the other hand, there were some post ROTJ Sith lords, such as Darth Krayt. So, the prophecy plotline is a bit contradictory, that's why I don't like it. The story would be simpler without it.
'Bring balance to the Force' - hmm, could have been. I suppose that's been retconned in the EU, and will have to be rectonned for the new trilogy because what's Star Wars without Sith villains?
The Chosen One was, if I'm not mistaken, foretelling the Rule of Two and the fact that Sidious and his master's plan to bring the destruction of the Jedi would actually work, unlike all of the other tries. The Chosen One was corrupted, but he eventually brought balance by taking out the man responsible for the death of all the Jedi and swaying the galaxy toward the dark side. Sith existing does not equal no balance. Thus, Sith can still exist after 6.
Yah, with the new trilogy on the way, I doubt the prophecy is going to matter much..well I'm ok with that, I was never to fond of that stupid prophecy.
Star Wars fans also once thought that Luke's father had been killed by Darth Vader. Things can change. It's not out of the realm of possibility that a force sensitive being can take up the ways of the Sith after Episode VI.
I intended this thread to be about GL's 1999 intent, but what they'll do with it in the ST is an interesting topic too.
The prophecy idea was only born in Episode 1. I think that's what @Klingon Padawan was referring to. Those who watched the OT first just saw Vader as one Jedi of many, who decided to betray and murder the others. Then all of a sudden it turns out he was this prophesized Chosen One. I think the saga could have been successful without the Chosen One plot, but I don't think the story suffers at all with the importance placed on Anakin.
Personally, I believe that the Prophecy enhanced the story of the films. Placing so much importance on Anakin Skywalker made his fall to the Dark Side even more tragic. To someone viewing the prequels first, it seems as though Mace Windu was right and Anakin was not ready for this task and that maybe he was not the Chosen One. To those who saw the originals first, the tragedy lies in the fact that so much evil had to be committed before Anakin could actually fulfill his destiny (with the help of his son) and destroy the Sith.
I also like the idea of the prophecy. I believe it adds to the mythology by adding a guiding force to the story, other than sheer coincidence.
Vader was not a main character until ROTJ. So making Vader the "Chosen One" destroys Vader's sacrifce- it was intended to happen all along. And wouldn't Obi-Wan mention the Prophecy to Luke or at least Yoda in the Originial Trilogy?
It is shown throughout the prequels that some Jedi, Mace Windu in particular, never never had much faith in the fact that Anakin was the Chosen One. Yoda himself even said that the Prophecy could have been misread. When Anakin became Darth Vader in Revenge of the Sith and committed such evil deeds as slaughtering younglings in the Jedi Temple, Obi-Wan and Yoda more than likely agreed that Anakin was not the Chosen One (note that, in Return of the Jedi, Yoda wanted Luke to confront Vader, not convert him from the Dark Side) and thus would have no reason to mention the Prophecy to Luke.
