Darth Spoiler.

In a losing bout with the Dark Side, I broke down and read the full Episode III: Revenge of the Sith script last night (as well as the last chapter of the novelization.) Obviously, massive spoilers involved, none of which I'll recount here. But I'd say that, at least on paper, the groan-quotient is lower than in Episode II, although the movie does start off somewhat ham-handedly. And, as with Episode I, there are a number of clunky "let's take a meeting" exposition scenes throughout that I could see coming off rather badly. But, given the action setpieces herein, this should probably be the best of the prequels...or, at least, one hopes.
