Hereditary is the horror film that has been described as a ‘ride of pure terror’ and likened to The Exorcist and Rosemary’s Baby and The Shining, to which I can say only: in its dreams. Given I’m such a wuss when it comes to anything frightening — the child-catcher from Chitty Chitty Bang Bang still scares the living daylights out of me — I’m rather thankful, but I’m perplexed as to why it received such rave reviews.
