Pretty bad.

Rating: 3/10 (23 December 2018)

The acting is generally very good. Except from Gabriel Byrne, but he doesnt have much to do in it. Alex Wolff and Toni Collette are outstanding as the tormented son and his mother. The weird looking Milly Shapiro, who seems to be the lead in the very misleading trailer, is okay, but shes not much in the movie. And the movie is more weird and ridicouluys plotwise, than it is actually scary.

*MAJOR SPOILERS AHEAD*
It starts with Annies (Toni Collette) mother who has just died a while before the movie starts. They go to the funeral.
A few weeks later, Charlie (Milly Shapiro) who is allergic to nuts, is forced to go to a party with her older brother Peter (Alex Wolff) At the party she eats cake with nuts in it while her brother smokes weed with his friend. Peter rushes Charlie to the hospital , but they never make it there. Charlie cant breathe and opens the window. To avoid hitting a dead animal on the road, Peter makes a hard turn and Charlies head hits a post and she is decapitated.
From this scene on, the movie gets really weird and really bad. Now instead of calling an ambulance and the cops and his parents, like a normal person would do, Peter drives home to his parents, house with his sisters headless corpse in the backseat and goes to bed. This is not normal behaviour in a situation like that. The next morning his mother finds Charlies corpse in the car.
She starts goes to a sorrow group therapy session. At the group she meets the seemingly nice Joan, who later on tricks her into a spiritual session that awakens one of 8 kings of hell. Apparently Charlie was never Charlie. She was this demon king. Her body was just a temporary vessel and the older brother Peter is the vessel the demon prefers at it has to be a male body.
And appeearently Annie and her brother, that killed himself as a teenager were nothing but pawns in the late grandmothers scheme. She was a satanist (whos only goal in life was to give a body to the demonking) and leader of an insane satanist cult, whose members walk around naked when they perform rituals. So appeerarently this plan to resurrect that demonking has been the cults plan for at least 45 years. Yes its that ridicoulus. And it's very long.
I dont mind major twists in horrormovies. That is usually what makes them good. But it's just not believabe that this had been planned for nearly 50 years and the grandmother only had kids to have vessels for the demonking.
I'm only giving it 3 stars, because of the acting from the two leads and because of the cinematography, which is also really good
Don't waste your time on this crap.
