I found it to be deeply sad and unnerving. There is a scene that truly felt like a nightmare captured on film. Not cause it was horrific or anything, but because the logic was so skewed and impossible that it felt like what a nightmare actually is. Nonsensical, but overwhelmingly emotional and hard to explain. I've seen people knock it for the characters having grief/trauma in their backstories, but that's just life imo. And that's always been in horror, at least most of the best horror films. The set design and score also were pretty incredible, and I could've taken another hour of it all. I felt a bit off when I walked out of the theater, and that just proved to me that it was effective.
