The venerable Burning Man Festival has nothing on the art house stylings of Ari Aster’s Midsommar (B-), in which a group of Americans including Florence Pugh, Jack Reynor and Will Poulter visit the fictional Swedish commune of Hårga for what detours into the realms of hallucinogenic revenge fantasy. This curiosity, buoyed by eat/prey/love storyline stanzas, is more trippy than terrifying and more symbolic than satisfying. The highly effective Pugh plays a complex woman recovering from family tragedy and talented Reynor her overwhelmed lover. Their date with destination goes a bit far afield; and despite the generous running time, it rarely is uninteresting. Poulter is delightful comic relief as the friends find themselves drawn deeper into the shocking traditions of the countryside cult. But the film peaks early and can’t quite maintain its sense of mystery and dread. One of the film’s winning gimmicks is that most of the horrors happen in broad daylight in a setting that stays sunny. But only the most daring or devilish moviegoers will revel in the film’s bonkers final act. Applause for the intellectual take on the horror genre and the creation of an original world; but it ultimately needs a little more seasoning.
