Midsommar
Several friends travel to Sweden to study as anthropologists a summer festival that is held every ninety years in the remote hometown of one of them. What begins as a dream vacation in a place where the sun never sets, gradually turns into a dark nightmare as the mysterious inhabitants invite them to participate in their disturbing festive activities.
Horror is fundamental to the film's identity: the unsettling rituals, fear, dread, and grotesque imagery drive the experience; while there is drama and relationship dynamics, removing horror would remove the core experience.
Best for viewers looking for a scary, atmosphere-heavy, psychological and slow-burning horror movie.
