Honestly, it just goes to show that Sir Alec was devoted to his craft. He played the role well even though he disliked it. He did his job, and didn't let his personal feelings of the material get in the way of doing it right.
This compared to some of the other actors who were such fans they would do anything and not necessarily that well, just because they got the "privilege" to be in a Star Wars movie.
So no, it doesn't bother me that he didn't like Star Wars, I just have a different taste than the late veteran actor. I can respect his opinion while disagreeing with it. But only you know what you like!
