I thought this was a masterpiece until.....

Rating: 7/10 (26 June 2018)

This film grabs you by the heart, then twists, squeezes and chokes you until you think you can't bear it any more. The visceral, cloying nature of the horror is masterfully executed, and the first shock, about 20 minutes in, might make you cry, be sick, or both. Toni Colette gives us her best performance, which is really the be all and end all of the film, as, whilst the other actors are good, she devours the screen and then spits it out in a nuanced, devastating explosion of emotions, both restrained and unfettered.
BUT... the last 20 mins or so should never have been made, as we reach levels of ridiculous (LaBute) Wicker Man hilarity which, for me, totally ruin the entire endeavor. Most of the audience were howling with laughter during the denouement, which at my most generous I could deem to be a deliberate release from the preceding, relentless suffocation, but I doubt this is really the case. I think they were trying to do a Rosemary's Baby, and it fails.
