Although this is billed as a thriller/horror film, I'd place it more in the category of Black Mirror or Twilight Zone in that it's a satire about the state of things in the world, told with surreal/absurd elements. For example there were themes of people being disbelieved, while holding to an every-person-for-themselves attitude, further preventing people from getting support. There's much more to it than that (gender and class) so I'm summarizing very briefly.
Other points: Some of the acting was stiff at times but that became an advantage during brief kafkaesque scenes of the protagonist attempting to communicate. With surreal elements, it often comes with the territory in any case. The music was minimal and rather than announcing everything that was about to happen, it left space for the imagination to fill in the blanks, only containing a few themes that repeated, along with a few key visual leitmotifs.
I can see how a person following this as a literal story with a straightforward protagonist might expect things to go differently, but I felt a definite tension leading up to the end, wondering how the director would play out the themes presented in the story. Perhaps intentionally on the part of the director, while I felt sympathy for the main character, I felt even more for a few of the side characters, especially toward the end of the movie.
Overall I enjoyed the movie, found the themes timely, and will look up other movies by this director.
