"Anything that has to do with robots, aliens, fancy gadgetry, rocket ships, and space travel"? Who were you quoting there? That certainly wasn't me. As for the definition of "science fiction" not being open to debate, that's really not true. Where did you find your definition and what makes it the definition? I personally like the definition you provided but I also pulled this one out of the American Heritage Dictionary: science fiction n. A literary or cinematic genre in which fantasy, typically based on speculative scientific discoveries or developments, environmental changes, space travel, or life on other planets, forms part of the plot or background. sci'ence-fic'tion (sī'əns-fĭk'shən) adj. Hmm, sounds like Star Wars might fit under there.... Anyways, this is all just nit-picking. I'm just tired of people making these definitive statements about what genre a film is like they're the final word on the subject. It's not always a black or white choice- there are gray areas especially when trying to stick a film into a single genre.
