Ari Aster followed up his breakthrough hit Hereditary with the terrifying Midsommar, the story of how a summer trip with friends can go very, very wrong. Recovering from recent family trauma, college student Dani (Florence Pugh) joins her emotionally distant boyfriend Christian (Jack Reynor) and his anthropology PhD student buddies Josh (The Good Place's William Jackson Harper) and Mike (Will Poulter) on a visit to their friend Pelle’s (Vilhelm Blomgren) rural Swedish commune to experience a special festival held only once every ninety years. It's not long before they are all confronted by the secretive, drug-addled rituals of what seems to be a pagan ancestral cult, and what part they each must take.

Flower crowns haven't looked this sinister since The Wicker Man. Midsommar continues Hereditary's exploration of grief and trauma, emotional ferocity and occult practices but beautifully places them in the eerie near-constant sunlight of Swedish midsummer. Aster has gone deep on the research into Norse mythology, with telltale symbols and practices scattered throughout the film. Beware, the gore factor is thoroughly deserving of its R18 rating.
