The point is, he toes the line of whatever the official canon narrative currently is, but if the official canon narrative is defective and contradictory, then that doesn’t mean much.
Yeah and that’s basically the point of his entire blog. It’s about viewing Star Wars from a Word of God perspective.
I have my own head canons. To me, the sequels aren’t canon, especially TROS, which makes absolutely no sense and probably has some of the most plot holes of any sci-fi/fantasy screenplay. And he has head canons too, if you look at his blog long enough. But for the most part, he talks about Star Wars from a “Word of God” POV and always clarifies when he’s not.
Of course, though, the whole concept of “balance of the Force” is needlessly confusing, in my opinion. The word “balance” implies some sort of equal duality, and since Sith are the opposite of the Jedi, it’s no surprise that people would interpret the Sith as being part of that duality.
It’s called balance because naturally there is supposed to be both light and dark sides of the force. The problem with the Sith is their end goal is always to conquer the entire galaxy and subvert the force. To plunge it into complete darkness. There’s already enough evil going around without them.
I do agree, it wasn’t explained well in the films at all. They do say that Anakin needs to destroy the Sith and bring balance to the force but they don’t explain what balance means in this context. This is another example of Lucas underexplaining things to stick to the bottom line of the story. The funny thing about this method though is more then anything it actually distracts from the point he’s trying to make. He made the prequels to teach people about letting go but now all people talk about is how Anakin was totally in the right because the Jedi are actually emotionally repressive bullies. Because people are desperate to fill in the blanks and his flat dialogue and “tell, don’t show” approach doesn’t give the right impression. The prequels desperately needed an additional writer (contrary to popular belief Lucas did co-write ESB and ROTJ).
