Read that interview that I linked to. The prequels were gonna be awesome. George Lucas just sucks are a writer/director.
IGNFF: Well what were the original outlines for the prequels? Since they can be compared and contrasted now that the first one's out there, and the second one's soon to be out there. Were there major differences from what you saw, from the original outlines of prequel ideas?
KURTZ: Well a lot of the prequel ideas were very, very vague. It's really difficult to say. I can't remember much about that at all, except dealing with the Clone Wars and the formation of the Jedi Knights in the first place – that was supposed to be one of the keys of Episode I, was going to be how the Jedi Knights came to be. But all of those notes were abandoned completely. One of the reasons Jedi came out the way it did was because the story outline of how Jedi was going to be seemed to get tossed out, and one of the reasons I was really unhappy was the fact that all of the carefully constructed story structure of characters and things that we did in Empire was going to carry over into Jedi. The resolution of that film was going to be quite bittersweet, with Han Solo being killed, and the princess having to take over as queen of what remained of her people, leaving everybody else. In effect, Luke was left on his own. None of that happened, of course.
