is to exclude derivative works. I'm trying to think of an original Sci-Fi + Horror concept that doesn't draw on the above list and am coming up blank. E.G. I liked Demon Seed, but it draws a lot from Colossus: The Forbin Project.

Also I think Horror and Sci-Fi started to bulk up in their respective venues over the past 25 years to the point that you don't really market Sci-Fi AND Horror anymore.
