I think that all questions like this and raised in this thread could be answered by...."George Lucas just didn't care enough to see the movies again before writing the prequels, cared more about having a guy filming him as he sat down to write Phantom Menace than taking some care to not confuse us, and probably just doesn't care at all about the problems".
I was just reading that GL wrote to the Lost writers, saying that he didn't know where his stories were going either, and he just wrote. I think that was best kept quiet, personally (same thought when Hayden Christiansen said something about how he just didn't take the movies seriously enough to try to act well in them).
My brother and I were just having many of these conversations yesterday by the way...good timing!
Here's another one. On Dagoba (where Luke meets Yoda for training) and he is about to leave to go help Leia and Han, ehtereal Obiwan says to Yoda "He is our last hope." Yoda says "No, there is another." (speaking of his sister Leia). Should Obiwan already know this? For goodness sake, he WAS THERE when they were born.
Good call, but I guess the ONE thing he might not have known is if she had any Jedi powers.
At least Episode I. I never understood why...if the goal was to keep Luke hidden from the Emperor, why they would choose to raise him on the same planet where his father was the first human to win the Pod Races thirty years prior. I MEAN REALLY!
Actually, in hind sight, I think Yoda was talking about Anakin/Vader in this scene, not Leia. Ultimately it was Vader who killed the Emperor, not Luke or Leia.
The prophecy that Anakin would destroy the Sith turned out, ultimately, to be true. In Episode III Obi-Wan says to Vader "You were the Chosen One! You were supposed to destroy the Sith, not join them...Bring balance to the Force, not leave it in darkness!" Well, that is what happened in the end.
I think that's a good philosophical discussion, but I just really doubt that it's what GL was thinking.
And DH and I have had the discussion that Vader being "bad" does indeed bring things into balance, because by the time of A New Hope, it's Ben, the Emperor, Vader, and Luke (and Leia but she doesn't know) since all the other Jedis have been killed off and there don't seem to be any more Sith. Fairly balanced.
Face it, its a movie, or a series of movies, and the continuity is not going to be perfect, especially when the movies were made out of chronological order.
Since they were written by one person, that's a hard one to sell to me. He's had decades to come up with quick and easy ways to explain stuff. In episode 3, have someone mention that Jedis are fully aware with memories from the moment they are conceived, and BOOM there's your answer to how she remembers whiny wimpy Amidala.
Who shot first - Han or Greedo?
Gotta tell ya, the digitized version is much easier to let DS see, just b/c Han isn't being the aggressor there...but of course as adults Han is much more Han when he shoots first.
