Have you pre-booked your tickets yet Johnny?
Even in the prequels, the idea that Yoda was aligned with clone troopers--it was like, "wait, am I supposed to be rooting for them? Or not? This isn't as fun, since I can't just let go and enjoy the ride."
Well since you know where it's going no you're not suppose to enjoy it in that way, you're suppose to dread the inevitable. It dawns on you that the frikkin Nazi soldiers who can't shoot for toffee that you saw everywhere in the originals were actually designed as a force for good, for peace, welcomed by the senate and the Jedi with open arms, it's drama, it's loading the gun that will kill you. It inverts your expectations to the upmost, to a fault.
The political manoeuvring was very interesting to me, one of the best things about the Prequels - How does Democracy fall? If you think about it the bad guys are in charge at the start of the original three films right? Pretty logical, easy story to tell from that point on. BUT, what do you do when it starts with the good guys in charge, it's not an easy route to the simplistic good vs evil sugar rush that you're looking for. The bad guys are the rebels, the bad guys are the underdogs, the good guys are smug, lazy and naive. He didn't have to make it that way and it took some balls to do that. Aside from anyones thoughts on the dialogue, CGI, acting etc, Lucas had that story down like a mother.
