Sure, but I don't think you can say it was just a matter of point of view when slavery was a fundamental element in it all. I realize the matter is much more complex than that--I'm remembering a Simpsons episode where Apu starts getting into the issues behind the war and the bored citizenship examiners cuts him off and says "just say slavery." Anyway: both the ficticious Star Wars war and the real-life American war had their share of clear bad guys that are behind some of the main causes. The prequels try to at first paint it as point of view, but in the end it doesn't turn out to be the case.

Anyway though, your point about the PT/OT thing is spot on, the OT was designed as a classic moral absolutism tale--good vs evil--and the prequels, to give them credit are pretty clever deconstructions of that, which would be fine if they are sequels, but if they are supposedly meant to be watched first or at least chronoligically come first then that doesn't really mesh well/
