Threepio kept quiet because he had NO MEMORY of what happened in the prequals (that is proven in Luceno's recent book Dark Lord: The Rise Of Darth Vader).
The Prophecy of the Chosen One meant that the Lightsiders (Jedi) and Darksiders (Sith) would be brought into approximate numerical parity -- Oh no. You couldn't have missed THIS point more if you & the point were moving in opposite directions. "Balance" has NOTHING to do with numbers of surviving Jedi & Sith. How ANYONE can think that is beyond me. Let me try to explain this in a "modern day" situation. (you need to be a bit open minded to get this, and I'll ASSUME that you are). In modern society, The Government is in control, and the police enforce the law. When the criminals are running the streets, and their is anarchy, things are out of balance. Now, Obviously the Senate (along with the Chancellor) are the government, the Jedi are the Police, and the Sith are the criminal element. When the Sith are in control, and dominating the galaxy, the Force is out of balance. Balance is the status quo. While it's not perfect, the criminals (arguably) are not in control. Anakin DID in fact bring balance in ROTJ by ending the reign of the Sith, and putting the Government back in charge. (Yes, I realize this is a "perfect world scenario where the government aren't corrupt).
Qui-Gon Jinn knew what "balance" entailed. Of Course he did. Qui-Gon could see that something wasn't right, and the the Sith were growing in power. Did he forsee that Anakin would give himself to the dark side and kill his friends & co-workers? Of course not! While Qui-Gon often disagreed with the Jedi Council, his loyalty to the order was NEVER in question. To suggest that Qui-Gon would make his dying request to his padawan to train someone he foresaw murdering everyone he knew is not heresy, it's just plain stupid.
The Jedi were evil and deserved to die.
-- No. The Jedi were full of themselves, and misguided, but they certainly were not evil. Keep in mind that thanks to the EU, the Jedi Order has gone through several incarnations. Each one with thier own sets of rules. The Jedi Order we see in the PT, is just the current incarnation. However, in EVER incarnation, the Jedi have ALWAYS been, "The guardians of Peace & Justice in the galaxy" or, for lack of a better term, POLICE. The job of the police is to go where the government tells them, and enforce the laws.
the Jedi and Amidala collaborated to fake her death
- Bullshit. As much as I HATE it (because it contradicts ROTJ), Padme is dead. There was no faking of her death. End of story. (Read THE DARK NEST TRILOGY to see how Luke finally finds out about his mother)
As far as your comments regarding the Expanded Universe.....
Timothy Zahn's books are boring.
-- You must have the attention span of a fly. Zahn's books were brilliant. Granted, "Survivor's Quest" is a little slow at times, but Zahn was a perfect choice to START the EU. Further more, Zahn worked VERY closely with West End Games (THE Authority at that time) to make sure there were NO lapses in continuity when he used established species, and technology. This brings me to our next point....
Kevin J. Anderson was right
