I saw it today..great movie. Especially when Yoda force throws those two royal guards into the wall, good shit. I also Expected General Grievious to be more of a menacing character, judging by the cartoon, but hes this coughing, weezing guy who gets cut down and stabbed through the heart in a matter of 5 minutes. Its a dissapointment, Grievious seemed like a badass.
A new hope really made a lot more sense to me after Revenge of the Sith. I mean, I knew BASICALLY what happened that led up to a new hope, but the stuff like when Vader and Obiwan are fighting in the Death Star in A new hope and vader is saying things like "We meet again" and "this time i will be the master". Things like that clicked more now.
Seeing Ep. 3 also made me realize the transition between the republic and the empire more and more. I had always thought that the Separatists turned into the Empire and Republic turned into the Rebels.
So in conclusion, the entire OG series (a new hope, empire strikes back, return of jedi) makes a lot more sense to me now
