The six Star Wars films form the greatest postmodern art film ever made (kottke.org): "Aidan Wasley argues that taken collectively, the six Star Wars films form the greatest postmodern art film ever made."

Mr. Kottke has not provided a comments area for this link and probably with good reason since this would be one huge-ass thread. I don't want to link to Slate directly because of their idiotic pop-up hell, but Mr. Wasley writes in the opening paragraphs that Star Wars is about plot and the mechanics of storytelling itself. That is far-fetched. I really don't feel it is a "meta" anything. It is about what it intends to be about and nothing more. He states that the fact that the droids C-3PO and R2-D2 end up on Tatooine is a huge coincidence and proceeds to build his argument upon that. The problem is, for all the praise Mr. Kottke gives him for attention to detail, this is NOT a coincidence. R2-D2 KNOWS where Luke is. Only C-3PO had his mind wiped at the end of episode III. They both stay with Bail Organa and Leia.

The protagonist of the whole cycle is really R2-D2.
