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.
RE: Weapons (film): It's good, but is it as good as they are saying?
