An authentic hippie midsummer

Pleasantly close in atmosphere to Robin Hardy's The Wicker Man (1973). In both films, outsiders are lured into pagan ceremonies in some remote corner of the world, where beneath the people's overflowing happiness, there lives some kind of inexplicable evil. And all the evil happens in broad daylight and in full view. No ghosts in the dark and no knife-wielding lunatics in masks. Ari Aster's Midsommar may well as well start to gain some sort of cult status because this is an extremely impressive film.
