Prequel Trilogy lovers will appreciate this article I think, and Prequel Sceptics like myself can actually take a lot from it too.
The article's title is a little misleading, as it's not really about Lucas's authorship, and is more about the story itself. In essence, this article centres around the "balance" in the Force, and the ostensible "goodness" of the Jedi in striving for (but actually preventing) said balance. The author sees a lot of nuance in Anakin's role in this, claiming the binary logic of the Jedi and the Sith forces Anakin's choice to go to the Dark Side.
The article is easily the most persuasive argument I've seen for character development and moral complexity in the PT. I agree with the author that Lucas might not have known what he was doing, but given that we've got to work with the final product...this is a really neat addition to the philosophy of that time in history.
