James Arnold Taylor does seem to do a good Obi-Wan Kenobi. The trailer looked pretty good, but it was so... dark that I could barely see anything. But it had me pretty impressed until that incessant "Roger, roger" sequence of droids at the end.
I swear my favorite moment of Revenge of the Sith is when Palpatine said that all droid unit must be shut down. I literally shouted for joy in the theatre I hated those things so bad. ^_^
