I'd put that as one of the best moments in the entire saga.The opera house scene might just be the best moment in the entire prequel trilogy.
I thought Episode III was the only respectable of the 3 movies. The Phantom Menace is ok but it really drags at times. Attack of the Clones is tainted by bad acting, a weak plot, and one of the worst love stories I've ever seen on film. Episode III still had faults, but I felt like those were only particularly noticeable if you really thought about them. Taken at face value, it's a great movie. Loved all the action (the opening scene really harkened back to what made the originals so great) and the story parts were actually interesting.
