Katla (2021)

Set in Vík, in the south of Iceland, more than a year into a nonstop eruption of the glacier volcano Katla, this series has people walking down off the ice covered in sooty clay, and nobody can say what they are. It is adapted from an old folk tale, and the Nordic folklore at Iceland's roots, rather than monster effects, gives those arrivals their unease. A small town living in the shadow of a volcano is a setting like no other on this list. The first two episodes are slow, so give it time to take hold.
