stuff like little otik, candyman, mama, most of the movies about humans turning into creatures like the reptile, some exorcism movies, some evil scarecrow movies, some hammer stuff, the blair witch project (somewhat debatable but not really imo) and a lot of other more straightforwardly supernatural or gothic witch/occult movies, various werewolf movies, some fairytales like little red riding hood, hansel and gretel, the wolf house etc. stuff like bergman and marketa lazarova also gets cited, may have the folk element down but it's not really horror. granted a lot of these have it as a secondary rather than primary genre on rym but i'd even dispute that in a lot of cases (stuff like hot fuzz is spot on though). i've been through the whole list not long ago and discarded probably half of them as not seeming relevant, but obviously a big portion of those i haven't seen so i was going by synopsis and reviews. the most common issue was people arguing that a mermaid or werewolf or minotaur or -insert mythical creature here- automatically makes a movie folk horror, which i don't agree with.
