Somewhat disturbing but great suspense

Rating: 8/10 (10 March 2019)

I am not sure if this movie is a typical horror movie - in a review I read it was compared to "the shining", but it is a superb enable of tension - building psycho thriller.
The story offers so many layers that you can easily watch it over again from a different point of view from the protagonists.
I am still not sure, though, what role the dead mother /granny played. I think I have to watch it over again.
