The term "folk horror" might not be the easiest thing to describe, but it's the type of horror movie where you know it when you see it. There's even a recent documentary called Woodlands Dark and Days Bewitched: A History of Folk Horror that spends a little over three hours explaining what this type of horror subgenre is and exploring some significant films within it. Put simply, though, this horror subgenre usually features rural/mostly outdoor settings, and explores themes and stories that surround European pagan and witchcraft traditions/folklore.
