As a huge horror fan, the deep realistic portrayal of how terrifying human beings' minds can be makes psychological horrors my very favourite horror typed genre to watch. I had very high expectations for this movie and it did indeed tick all the right boxes! This movie is so well written, directed, set and acted - from the eerie music to dark surroundings, this movie has no faults whatsoever. The history and youth of this film is such a brilliant visual education factor. And the story is so well explained and acted that it is, without a doubt, a must watch!
