Space ships and aliens doesn't make a story science fiction. Star Wars is not SciFi Fantasy. It's just fantasy. If you want a sub-genre of fantasy... fine... call it Space Fantasy or Space Opera. It's still not Science Fiction.
:) Now... Star Trek (though many of the episodes and films are ridiculous and don't fit with correct understanding of science, buck)... THAT's pure science fiction. It would be a much better inclusion than Star Wars on this quiz.
