Y'know?... me too... I was listening to the ROTS soundtrack in the car today and as it played I imagined scenes in my head, the way I would have made them... and I have to say... it could have been a little more emotional and dark. They dipped into it for a moment at the beginning and end of the duel, as well as Obi's visit to Padme when was hunting Anakin... But I still think they could have played it up a little more.
Anakin knew what he was doing, he HAD to be able to sense that Palpatine wanted him to do evil things. Even though they made sense to him at the time and he thought he could save Padme.... He knew killing his friends and destroying the Republic was going to be "not good". In the movie as it stands he was not emotional enough, and Obi-Wan deserved more explanation than just....
"I've brought peace and stability to my new empire..."
"If you are not with me.... then you are my Enemy..."
I would think that two LIFELONG friends would have more to say to one another while they fought. Vader seemed to have PLENTY to say to his son when he fought him on Cloud City... and he knew almost NOTHING about him.
I know it's a bit of Nerd Blasphemy... but I would have loved to see what ROTS would have been like through the vision of Peter Jackson. He knew how to great good drama, make grown men want to cry... He would have done those scenes justice.
disclaimer: ROTS is one of my favorite movies.... so remember... I am not bashing it at all....
