Second. The music. A while ago (it might have been in this thread, i'm just too lazy to check) someone posted a clip of the battle between Darth and Obi-Wan with the Battle of Heroes music, and thought it was great, and still think that. Here's the way I see it: Back in 77 when Williams was scoring the movie, Star Wars was a very different movie. Darth Vader and Anakin Skywalker to him and the audience were two different people. Vader was simply a bad guy, albiet a really cool one. There was no conflict of good in him. When it came time to score that scene, there was no reason to make it that emotional up until Obi-Wan dies. Fast forward to today, we have five more Star Wars movies, three of them devoted to the lives and relationships of those two people fighting. We are now emotionally invested in these two characters, knowing they had a teacher/student relationship, father/son-type relationship and a brother-brother relationship. If we watch the movies as a whole, that duel on the Death Star is missing something. It is the final battle between these two former friends, and there is no music at all just an old man and a machine. I personally believe that if A New Hope was made today Williams would put in a Battle of the Heroes bit of music in that scene. Sure, back when it came out it was devoid of music for a reason, however, today there are very good reasons for putting music in that scene.
Plus, this is Adywans edit, he can do whatever he wants. If he wants to replace all of the actors with Ewoks (or Gungans for that matter), then that's his perogative. Granted that would be a terrible perogative. We'd hunt him down and break his legs.
