From the very first opening minute there is a creepy atmosphere to the psychological horror 'Hereditary'. We are introduced to Annie played with great conviction by Toni Collette who is just about to bury her mother. We get the distinct feeling that Annie didn't particularly see eye to eye with her and is struggling to grieve for her loss.
Through the course of this we get introduced to her slightly strained family. With her put upon husband Steve (Gabriel Byrne) and her estranged son Peter (Alex Wolff) and Strange daughter Charlie (The underutilised Milly Shapiro). The creepy conotations build slowly - this movie is definitely a slow burn so if you like your horror fast paced it might not be for you - where we witness Annie creating life like miniature dioramas replete with tiny people and furniture. A production design that is used again and again in both setting and cinematography. At times it appears the characters are living in a real life doll house and we are viewing them first hand. Its a clever and weird device.
The movie is quite atmospheric and tension slowly builds. At first you aren't sure where the movie is going, building up the supernatural elements slowly. Only when Charlie is horrifically decapitated by her brother Peter by accident - a scene that's brilliantly handled - does the movie show any real momentum. From here there is some terrific scenes with Annie as her downward spiral where it is heavily implied that she had a breakdown of some sort and has never quite recovered all of her mental capacity. In one shocking revelation she admits to her son Peter that she never wanted him as a child in fact she tried to abort him on numerous occasions but failed primarily because her overbearing mother wanted him and not her herself.
As tensions rise and the family unit deteriorates old secrets rise to the surface and home truths that are pushed from the surface come back to haunt you and that trust that was once there suddenly evaporates and you can never really get it back. To say any more would spoil the movie.
I would say that Hereditory is two thirds of a great movie with the final third the least satisfying. When you learn the 'truth' of why the supernatural occurrences are happening it deteriorates ever so slightly into parody. Not to say that its bad, its not it just didn't have the same level of tension and the final reveal is a little bit on the silly side which might raise a few titters more than shock.
But still there is much to be enjoyed about Hereditary if, of course, you enjoy slow burning psychological horror. From a purely performance stand point Toni Collette is terrific and gives a powerful performance. All in all I quite enjoyed 'Hereditary' while not perfect it is worth watching.
