This is a good film. The other review on this film borderline calls people stupid for not enjoying the movie's slowness. It IS slow in parts, but that doesn't make the film not worth it. It also doesn't make you a simpleton for thinking so. And if you watch and rate it under a 7, I'm sorry to say that this film's other reviewer doesn't seem to understand personal opinion nor do they seem to care about anyone's opinion of the movie that doesn't 100% line up with their own.
That being said, the movie is wonderfully done, I'll give it that. It can be a little slow-paced but there's a point to that. It adds to the viewer's inability to figure out what's going to come next, and it does a good job of it. There are parts of the film that feel mundane, but I believe that's on purpose. Everything about this town screams mundane except Karen and her demons.
I definitely recommend it if you like a bit of uneasiness in your horror flicks. Do not watch if you are expecting to have everything explained to you or if you are wanting a fast-paced action horror film. This is a slow and methodical watch but it pulls you in almost immediately. Give it a watch!
