'The Banshees of Inisherin' Is a Pitch-Black Delight

The Banshees of Inisherin presents itself as a fable, and from its first frames we enjoy the simplicity, the distillation and instruction, which that form promises, however well we might know its dark side. We soar down through welcoming skies onto an island off the West Coast of Ireland. It is a fictional island, though only just: Banshees was filmed on the largest of the Aran Islands in Galway Bay, Inishmore; the smallest, a few miles south, is called Inisheer.
