Surreal but realistic horror which exceeded my low expectations.

Rating: 6/10 (4 September 2019)

In a lot of discussions, people will explain that they find movies about break-ins, serial-killers, torturers and the generally non-supernatural as scarier than movies about supernatural evil. I have always disagreed, until I watched this movie.
I expected some sort of horror show. Instead I got a slow (very slow) descent into madness. While I think the movie could have lost 20-40 minutes easy, I did enjoy it more than I expected. Losing control of my mind is much scarier than an intruder. There's bottomless horror there that you can do nothing about but endure and hope to retain your sanity.
The cinematography is never boring. Most shots are long and mesmerizing. I often caught myself wondering how long a shot had lasted, only for it to just continue.
There were a couple of great horrifying moments in the movie, which I will not spoil. But the pacing detracts from my overall enjoyment. The middle is great, everything else dragged.
