Although falling squarely into folk horror tradition, Ari Aster’s 2019 movie Midsommar establishes its horror by drawing on the family and its intricate connection to affective, that is both emotional and bodily, belonging. I argue that Midsommar outlines how the depicted cult’s sense of community stems from its practices of physical displays of compassion by juxtaposing the two storylines of Dani’s tragic loss of her biological family in the US and her subsequent absorption into a death cult abroad. Hereby, I seek to expand Rosenwein’s and Chaniotis’s concept of an 'emotional community' to that of an 'affective community.' This analysis of Midsommar sheds light on a form of personal apocalypse exploited and reinforced by the destructive powers of a death cult in its access to a new member, using her body and mind alike.
