If there's a highlight in this movie for me, it's the endless bickering it often showcases and which takes place often and among its different characters. Here, their animosity, hidden feelings, ambitions, cult secrets, and social missteps all come to the forefront in a weird and viscerally uncomfortable feeling. This covers everything in their lives from the moment when Dani and Christian, a university couple with a strained relationship, decide to go with their friends to Sweden and celebrate the summer solstice in an isolated commune.
However, as the main storyline of the film picks up speed - which is essentially the Wicker Man all over again - the movie loses this odd but definite edge it has. To make things worse, the ending itself is completely devoid of talking and focuses only on imagery. In theory, I can see how this should have been a huge, allegory of a deteriorating relationship, but the problem is that it took its sweet time getting there. For me, the same trippy experience exchanged bodily horror for some missed opportunities in domains of poetry and natural celebrations. And that won't do at all. After all, nature hates wasting time - just look at the mayflies.
