Depression, obsession and the deep abyss of the human mind

Rating: 10/10 (6 January 2019)

You're not gonna forget it. It's totally enough to watch it once. It's mutch more effective than a 'horror' movie. It doesn't have jumpscares (maybe one or two) but it is a horror. It shows what happens to a human if his/her inner demons take control on his/her body and mind.
I made a mistake by watching it as a 14 year old because on the day I watched it I was just starring in front of me and I was thinking a out the movie. Don't watch it under 18!
