Midsommar is packed with details that left a couple of unsolved mysteries and also made way for theories, among them one that claims Pelle (Vilhelm Blomgren) killed Dani’s (Florence Pugh) family as part of an elaborate and cruel plan. After the success of his feature directorial debut, Hereditary, in 2018, Ari Aster returned one year later with Midsommar, a folk horror movie that proved that horror doesn’t happen exclusively in the shadows of the night, taking the characters and the audience to Sweden to celebrate a midsummer festival like no other.
