In my personal view ghosts can't harm humans. They are from a different dimension and they cannot disturb us humans without God's will. Usually a ghost can get to humans or hurt humans through the means of humans themselves. So this movie clearly works around that in being a horror movie that does not need a ghost to be horrifying. I enjoy everything about the story. It is quiet cliche as I seen Jack character in other movies but hey this is totally in a different setting. Another masterclass performance by George Mackay a rising star.
