It's a reasonably comprehensive look at folk horror, seen mainly through the lens of movies.

The talking heads are all erudite and provide interesting bits and bobs throughout the hefty runtime. There is no real 'arc' to the story of the documentary - it's basically a chronological trek through selected folk horror stories from beginning to end.

If you happen to already be a fan of folk horror then this will be absolutely perfect for you - it's an intelligent and respectful look at the importance of our myths.

If you have only a passing interest, this doc won't make you love folk horror. It's humourless and only interested in chewing over the context and subtext of specific tales for hours and hours. Its narrow focus will likely bore some viewers to tears.

So I'd recommend it with those caveats. It's good, but deliberately esoteric.

All of the people interviewed were very interesting and informed. I'm more versed on Japanese folk horror, and I ended up writing down 20+ classic and modern films I want to watch. The depths they plunged into the subject was impressive and enlightening.

It's cut up into chapters, so if 3 hours of video is too much, you could write down the time stamp and chapter and resume it later.

Highly recommend to film buffs.

If you have even a passing interest in the world of folk horror, Kier-La Janisse's exhaustive exploration - which clocks in at 3 hours and 14 minutes and could have been thousands more if I had my way - is the film of a lifetime. From the unholy trinity that launched this trend on to screens - Michael Reeves' Witchfinder General, Piers Haggard's Blood on Satan's Claw and Robin Hardy's The Wicker Man - all the way through British television and films around the world, this movie is quite literally the last word in what folk horror is, what it means and how it's still part of the world of cinema today, perhaps more than ever before.

With more than fifty major names in the world of horror and horror writing - everyone from Amanda Reyes, Piers Haggard, Adam Scovell, Jeremy Dyson Samm Deighan, Kat Ellinger, Robert Eggars, Ian Oglivy, Kevin Kölsch, Dennis Widmyer and around forty more voices appear with great insights - there's never been a more well-rounded approach to tackling a movie genre within a genre. This feels like the kind of film that I'll be coming back to again and again.

Beyond the expected anchors of the genre, I was so excited to see lesser-known films get their due, like Alison's Birthday (which is on the gigantic All the Haunts Be Ours box set that Severin is releasing), beDevil, Dark August, Eyes of Fire (also being released by Severin), Grim Prarie Tales, Lemora (which seemingly has footage from the mysterious blu ray of the film that never materialized) and Zeder.

This is the kind of material that you want to pause, write down, make notes on and keep updating your Letterboxd while you watch it. This isn't just a movie about films. This is a true celebration of the magical wonder hidden within the flickering image, an exploration of a genre of all the dark old things and a journey through how each country documents the unknown through their media.

There aren't enough stars in the firmament out of ten to rate this one.
