Mean, irrational and dreadful. Sick of these horror movies

Rating: 1/10 (11 June 2019)

Ok, so we have the king of hell, some boofhead who is worshipped by some over-weight Satanists led by some matriarch who can't tell the gender of her grand-kids and so puts the spirit, or something, of this king of hell into the grand-daughter instead of the grand-son. And to rectify this the grand-daughter has to die, along with the husband of the daughter and the body of the dead grandmother and daughter have to be decapitated before the spirit of the king, who has been wandering around, naked, and clothed, with an imbecilic grin on his face, can take over the son's body. Have I missed anything?
The meanness comes from the suffering the poor family has to go through; the irrationality from the fact that it makes no sense for all this mundane mayhem to occur. If this king can inhabit bodies at will why doesn't he just do it? If he's dependent on some fat Satanists having to perform a SÃ©ance to bring him into reality he must be pretty puny.
Just dreadful; although the segment of Toni Collette lurking in the ceiling corner is ok
