Re: Star Wars Episode VII
On the "balance to the Force" thing.
First, I disregard Lucas' interpretation, because it's apparently all over the place, meaning alternately that the Sith are destroyed, and/or that there's balance between dark and light. So, yeah, I don't think he really knows and just threw in some stuff that sounded cool. Or he just changed his opinions periodically because that's what he seems to do, and whatever his whim was at a given moment was the latest interpretation of "canon." So, screw all that noise.
My view was less about dark vs. like, or Jedi vs. Sith, but rather passion vs. dispassion. If you look at the Jedi during the prequels, they're almost always dispassionate and very...reasonable. They think, but they don't really feel. Anakin, on the other hand, is a cauldron of boiling emotions that eventually boils over and he loses control of himself. My supposition (unconfirmed by anything I've seen that's regarded as primary canon) is that the Jedi took children as young as possible, so that they could be raised to be dispassionate and reasonable, because the Old Republic Jedi thought that was the best way to ensure that they wouldn't fall to the Sith. But with Anakin, he was taken at an older age, where he was already full of emotion. Fear, anger at being a slave, anxiety from being separated from his mom (never mind that he freaking chose to leave...), and so on. The Jedi were totally unequipped to contain this, and ended up losing control of him.
I tend to think that Luke is the one who ultimately finds the balance in the Force, in that he's emotional, but calm. He doesn't ignore his feelings or repress them, but he doesn't let them control him either. That's what I think was missing with the Jedi. They repressed or ignored their emotions, whereas the Sith just gave into feeling whatever, whenever, and doing whatever they please.
