The Mystery channel keeps promoting an inexplicable line-up of movies like Austin Powers and Undercover Brother by calling them "madcap mysteries." Right. In that vein, Scream isn't a horror movie, it's a "comedy of death" and Lord of the Rings is a "western" because they're on horseback and American Pie is a "documentary of raw humor" and Bull Durham is a "musical of the heart" and Lost in Translation is "film-noir without the crime" or maybe a "war movie about the clash of cultures."
And Mulder/Scully is slash.
I know you guys can come up with more of these, far better than mine. Yes? Please? No?
ETA: The Mystery channel is now showing John Carpenter's Vampires with Jon Bon Jovi. Which is apparently not horror, but a supernatural mystery. Pinheads.
