At just over three-hours long, this densely packed documentary isn’t for those with a passing, unenthused interest in the genre. Unfolding much like a lecture from Miskatonic, Janisse assembles over fifty talking heads to examine what folk horror is and how it evolved. While some of those talking heads are notable filmmakers, like Robert Eggers and Alice Lowe, the vast majority are critics and academics of the subject. Prominent authors like Alexandra Heller-Nicholas or distinguished film historians like Abraham Castillo Flores break down the subgenre globally. This documentary doesn’t feature the standard crop of genre interviewees; Janisse intentionally sought out the most knowledgeable experts worldwide.
