the "folk horror suddenly everywhere" claim kinda falls apart when you note that the three films they cite came out in 2023 (Lord of Misrule), 2019 (Midsommar), and 2015 (The Witch), and the image they chose to use is from 1973 (The Wicker Man). It's a subgenre that's had a bit of a resurgence in the past decade, but it's hardly a new thing that's "suddenly" everywhere.
