I absolutely loved the first half of this movie as the tension was just off the chart and I had to even put in on pauze at some point just to lower my stress levels :-)
The last part as often in horror movies with an interesting plotline didn't fully deliver but I still highly enjoyed it and it takes a place for sure in the list of my favorite horror movie like It Follows, The Babadook, Talk To Me, ...
This movie is also one of my favorites. I love how it builds suspense. :)
