I have never liked the horror genre. That is, at least, what I have always said. Friends in the fantasy literature crowd would speak highly of H P Lovecraft, but I never even cracked a cover. I knew I didn't like that stuff. I knew this because the wrong kind of children liked horror movies when I was young - except for a few unaccountables, whose presence could be ignored. People could like Poe, I suppose, though I disliked much of him. Film buffs (we don't call them "buffs" anymore - what do we call them) liked Hitchcock. It was all too close to slasher films, women screaming, knives, and blood for my taste.
I was therefore greatly irritated when a director of horror movies, no matter how talented, was chosen to direct The Lord of The Rings. I was unlikely to rush out to see that film anyway for a half-dozen other reasons, yet I think an aversion to horror itself kept me away at least some of the 10+ years it took me to break down and at least look at it. The wheels were turning, however. Even in my staying away I did readily see that it would be necessary to get Shelob, and Nazgul, and orcs, and Gollum! Certainly Gollum, correct in a way that directors of musicals and romcoms might not be up to. Yes, I reluctantly admitted, castles and knights and horses were pretty standard issue in the movies and could be just good enough without much harm, and even dragons allowed for a certain wiggle room. But the Eye of Sauron, the Oathbreakers, and Barrow-wights needed to be portrayed with some skill, or the whole enterprise would begin to carry a taint of 1950's Japanese Sci-Fi movies.
Then too, Tolkien had given strong lierary support for the importance of monsters in Beowulf: The Monsters and the Critics. (Wiki article here. Though if you haven't read the original 1936 essay, this would be a good time. It changed Beowulf and Anglo-Saxon literature criticism immediately and unto the present day.) Monsters aren't quite the same thing as horror, so I was able to mentally separate those strains - but it's an evasion, really. LOTR may be an adventure story and heroic myth, but horror is never far beneath the surface.
This comes up because I am rereading CS Lewis's "The Dark Tower." Which...is clearly a horror story, and likely to be loved by horror fans who might think they wouldn't much like the author of the Narnia Chronicles. I note in passing that Voyage of the Dawn Treader, at least, has some passages that fit the horror genre. More to the point, the last, individual battle of Perelandra, several sections of That Hideous Strength, and the dark underside of the Screwtape Letters, obscured by the ironic and sometimes even humorous tone on the surface, are also much like the horror genre.
I'm not quite sure what to do with my horror of horror at this point.
