However, to look at this and see that as the overriding point of the trilogy is to miss the point: the one critical mistake that could've averted Anakin's fall and the empire's rise. He didn't use a condom. If Padme/Anakin had used proper birth control, Luke/Leia wouldn't have been born but more importantly Anakin would have lost his biggest motivation to go to the dark side.
So remember kids, for the sake of the galaxy, use proper contraception.
By the way, if you haven't seen it already, Episode three really is
That Good.
