I found Anakin and Vader to be very disrespectful to all of his masters. Obi-Wan, however, was the most honorable and heroic of all of them. And correct me if I'm wrong, but wasn't he in ALL of the movies? I think he was. He was truly the main character of the Star Wars series.
I also like his stance in episode III when he does the two fingers pointing at his target... SICK stuff!!
