Over the years, George Lucas has re-released each movie over and over with extended versions, director's cuts, "remastered" cuts, and so on. When he did the new versions of episodes 4-6 with new footage and updated special effects, he said in the directors comments and featurettes that he now had the influence and control to remake Star Wars as he originally intended. He also talked about how Luke Skywalker was supposed to be a young boy like Anakin was in the Phantom Menace but that Mark Hamill was forced on him by the studio because of his popularity at the time.
When I first saw Lucas' comments I thought how great it would be to get the "real" Star Wars that Lucas envisioned. In fact I think most people thought that. But if you look at the results of this poll, you can see that the most popular Star Wars movies were the ones where Lucas had the least creative control. The more control he had, the more childish and superficial the story and characters became. That's why I'm so glad that Disney took over the franchise. As this chart shows, the less involvement Lucas has with Star Wars, the better it will be for fans and the future of the franchise.
