“Häxan” is the most fascinating horror documentary I’ve ever seen

The picture is, for the most part, fantastically conceived and directed, holding the onlooker in a sort of medieval spell.

Swedish and Danish pictures easily hold the palm for morbid realism and in many cases for brilliant acting and production.

If a film made with then-nascent technology can help us bear witness to legacies of misinformation a century later, might we hope to better understand how to reverse technology’s role in modern-day moral panics?
