I gave ROTS a 9.
It is definately my favourite of the PT, form the space battle at the start, to the big duel at the end. :o
GL seemed to step everything up a gear for this, the final installment, so the saga could end with a bang.
And it worked. A thrill ride from beginning to end. A few weak scenes, but who cares?
Seeing the legendary battle between Anakin and Obi Wan was the highlight, for me.
I think there could have been a bit more about Anakin's transformation into Vader. That is, after all what the whole trilogy is really about. Those scenes were disappointingly short, IMO.
But still my personal favourite of the PT.
