I'm hoping, please dear god, that I don't end up dragging this entire thread off-topic, but that is a poor example. I'm saying this without bias, as someone who's not a fan of either series, but the whole Jedi/Sith thing is comically black and white, with the Sith being all Snidely Whiplash puppy-kicking monsters for no other reason than that they feel like it, and the story needed bad guys.
As far as I can remember, even that whole story with Anakin switching sides, which I assume was supposed to be morally deep, seemed to boil down to:
Anakin: They don't respect my power!
Sociopath: I respect your power, and I can make you stronger!
Anakin: Deal! *Murders some children*
Well the issue i have with your point here is that while you are saying this without bias you are also saying this without knowledge of the situation. The Anakin situation goes more in depth than that. There are a ton of characters in the Star Wars universe that live outside of the Dark/Light force issue. There are many struggles in the books about people's views on dark/light and how it isn't always so clear cut or easy. Dark/Light are just the extremes.
