It's weird and uncomfortable and hilarious, but it doesn't have quite the same effect as Hereditary. Hereditary built up to the little twist that made it such a gut punch, but this one throws a moment like that at you from the beginning. Grief and loss then become a driving force but without the film ever really focusing on them it all just gets lost in the general cult shenanigans. Said shenanigans are great though, precisely shot and filled with a potent mixture of dread and black humour, although he dreamy atmosphere and passive nature of the characters strip the scenario of some tension, even if the reality of the situation is quite frightening.
