Mikael Brønmo Hansen’s review published on Letterboxd:
I'm gonna go out on a limb here and say that I think something is wrong with Ari Aster.
Holy mother frick... When it was done I had to just sit back for five minutes just to try and comprehend what I'd just watched. It's taken me a whole day just to write this review, because I just had to let it sink in. Even though I saw Midsommar before this and knew what Ari Aster was capable of, I was still caught off guard. I still have no idea what actually happened at the end.
The mom, played by Toni Collette, was just the right amount of crazy. She wasn't like too crazy to begin with that it was unbelievable, but not so normal that it seemed unnatural that she becomes really crazy. She was amazing. The same goes for the rest of the cast. None of them were bad, except for one scene where the son, played by Alex Wolff, cries. It seemed really fake.
Ari Aster is an amazing director, and I can't wait to see (and be horrified of) what he makes next.
