Hmm… that’s interesting. I think Europa Report gets put into cosmic horror because of the tentacles. Chrons of Riddick I can’t recall as I saw it years ago and wasn’t impressed. What’re your thoughts on those two?Do you think Europa Report, The Chronicles of Riddick or maybe the original Solaris are in this vein?
For me, the key to cosmic horror is (usually) an unknowable antagonist. Something outside of whatever galactic Darwinian methodology is used in the playworld.
Upstream Colour is almost an inscrutable Cosmic Horror whereas In the Mouth of Madness is a more prosaic (but wildly enjoyable) expression. The Cabin in the Woods has cosmic horror elements at the end but I’d class it as a creolisation of genres.
However, like most things I suspect we draw our own definitions… just don’t let August Derleth near your manuscript…
Oddly enough, the dreadful Nicolas Cage Colour Out of Space was a mundane ‘alien’ story AFAIC than cosmic horror. (And, how that idiotic pratfall of an actor even had a career is quite beyond my capacity.)
