LOVED horror movies when I was younger and a non-Christian. But I think it was easy to like them because a) I enjoyed the thrill of being scared, and b) I didn’t actually believe demons existed.
Same, but never the blood and gore types, only the psychological and ones involving creepy old/weirdly designed houses. I still find abandoned houses fascinating, if I can look at them safely at a distance. And I compare them to other movie/book genres in this way: Good always wins over evil, whether it be in horror, murder mystery or romance plot.
