To sci-fi nerds, George Lucas was the best director in the world - that is, until he stopped making new films and began "messing" with his successful ones over and over again like a DJ remixing the same song ten different ways on one album. In other words, he became rusty.
Fortunately, Lucas won't be getting behind the camera for the next set of films in the Star Wars saga (for now), though that's always subject to change.
*And there was great rejoicing.*
