Hollywood creates worlds where there are aliens who come to Earth in giant spaceships, where average people can turn invisible and fly through the air, and where raccoons-with-an-attitude travel through space. Remind me again why it can't make a world where our heroes are just a little bit, um ... different-er?**Don't say box office profits. The fan bases of fantasy and sci-fi are insanely diverse across all spectrums and you know it, Mr. Hollywood Exec Man!
