I think it could go both here and the film history page, with different emphasis on each. But no, I'm not the original author; I merely moved it from an inconveniently titled page. Just out of curiosity, what would you put here, if not this? --KQ
I would put it on film genres, which now has just a list of links and no content per se, or perhaps on [film genre]? (which is probably where film genres should point). What I would put in an article called "film genre theory" is information about the field of film genre theory--people, their theories, their jargon, etc. --LMS
