Lucas has come out saying that he didn't write a science fiction story; he wrote a fairytale set in different dimension.

In part I can see where he is coming from, just because it has androiRAB, spaceships, stars and planets doesn't necessarily make it a sci-fi film. If you look at Romeo and Juliet, a romantic story set in the 18th century. Technically a period drama; yet there are modern versions of the same story - West Side Story & Di Caprio version.
Though given the prequels of Star Wars, perhaps he is right; they should be defined as comedies instead.
