Midichlorians?
Like I said--they make sense (perfect sense) even if it's flat, ultimately uneccessary storytelling. There's nothing at all confusing about them. And the Leia's mom speech in ROTJ (which isn't a prequel) makes just as much sense now as it did then, you know the rationalization for it just as well as I do, since it's been going around for the past 4 or 5 years on messageboards: The Force.
It's not that I'm not open to the idea. I was--when it first popped up about 4 or 5 years ago when people realized how this Prequel Trilogy was going to end. And back then, people were trying to figure out if you could "preserve the secret" for future generations, and it was then where all these story problems (including the Episode IV revelation) popped up. The number of problems is pretty much insurmountable. Ell's sort of on the closest track to being right, but really, the ONLY way to finish traveling down that path is to somehow show Obi-Wan teaching a padawan NAMED Darth Vader at one point. You'd have to shoot and cut in a little kid and fake some voice-over stuff to do it. And even then, it's still just spackle, because the fact there's a Darth Sidious, a Darth Tyranus, a Darth Vader and a Darth Maul sorta ruins that the jedi would let a kid named "Darth" anything into the temple, much less let Obi Wan train him.
