Like another commenter said, it's post-Christmas, time to get pedantic about Star Wars.

I find it hard to buy the idea that the climax of RotJ supports this idea. At the end of RotJ all is portrayed as having worked out as well as they possibly could have, and all because Luke has made the extremely deontological choice to not fight his father.

Does Episode III contain the phrase "Only a Sith believes in absolutes"? Yes, and that's why everyone hates it.
