My only beef with the ending...
I don't mind the music. It didn't matter that much to me either way. I liked both. I also didn't mind the revisit to earlier planets. I thought it to be a good way to come full circle. What BOTHERED ME THE MOST was Hayden Christensen at the end. Let's set aside for a moment that I just can't stand the guy. But I thought it should be "neither or both" on Anakin and Obi Wan. I don't even necessarily care which way they went, young or old, as long as they used them BOTH young or old.
But I still can't stand the sight of Hayden Christensen.
