Saw this at the Rotterdam film festival 2019, where it was part of the official Tiger Competition. It is not a variation on A Clockwork Orange (Kubrick 1971) or Funny Games (Haneke 1997) that I deduced from the synopsis, but very different. It kept us awake and let us suffer along with the candidate vicitims. I was glad that the recurrent encounters with the evil threesome were very different each time, luckily leaving out redundant repeats from previous instances, like the discussion in the car about B&B versus tent. The role of the white cat is not clear to me, maybe just a gimmick letting us wonder whether its recurrent appearances were intended to mean something.
There is no morale or message embedded in the story, other than Tobias and Elin stopping their previous mutual nitpicking in the final scene and visually were connected again. What still puzzles me is that only Tobias seems to remember the previous encounters with the evil threesome, albeit only part of it and only knowing that some awful things are about to happen again, contrary to Elin who has no reminescenses at all. On the other hand, we see Elin following the white cat in a nightly quest of her own. Another mystery is why the evil threesome pops up at places far away from the camping spot where the couple fled from, after a fruitless attempt to evade unhappy encounters like the previous.
All in all, a lot of things are not understood but may mean something. The movie does not make me long for a real explanation, however. The only morale or message that I could deduce from this movie was that the couple may have been at a breaking point in their relationship when the story started, but were visibly together again near the end after the dire events they went through.
