For me, favorite equates to unexpected. In order: 1) The defeat and immolation of Anakin on Mustafar: yes, yes, the ROTJ novel clued us in as to what generally transpired in "the duel," but I simply didn't think Lucas had it in him to visualize THAT level of brutally breath taking carnage. Bravo, George! 2) Palpatine versus Mace's posse. Freakin' AWESOME (if not largely unrealistic). 3). Padme's rumination - "you don't know the POWER of my soft side!". Once again, I did not think George capable of injecting such tenderness and heartbreak into a SW scene. 4). The Space Opera - as so perfectly noted previously, mainly for the dialog . . . Engaging, revealing, and misleading, all at the same time. And as is all too often the case, I agree with Massster SX3, in that SW and John Williams are inseparable, and the score definitely defines whatever we hold to be our favorite scenes.
