Nice review again, I always enjoy reading them!
For me, I scored it a 7.8/10 mostly because I rate movies purely on my enjoyment which makes it so that some 'stupid' movies get hight scores while some 'technical masterpieces' get low score. That said, I fully agree on your view, this one just fell below some of my favorite horror movies of the past decade.
I do look forward to the next movie of this director as I also liked Barbarian and the tension it had in the first half of the movie. I do feel he's a bit too much 'form over story' as both were told from an interesting angle with great tension early on but the endings kind of dissapointed.
it's always tough to end a movie, a horror movie normally has to end with some sort of resolution and it is interesting when they don't or have some sort of "bad" ending but that is open to its own sort of criticism as well. Think "Smile" and how that ends badly, but now we expect every Smile to end badly. it's a tough game the horror genre.
