EXTREMELY Overrated (summarized plot, spoilers galore)

Rating: 1/10 (6 July 2018)

Ok, so I was so looking forward to watch this, since the critics in Sundance called it "The Excorcist" of our era, so much people rated it like the best horror movie in years, an so on. So, I watched with really high expectative. Here's what I saw:

We have a family of mother, father, son and daughter, who start the movie in the grandma's funeral
Grandma liked to do small models of houses, rooms, people and stuff (or did she? it's not completely clear, but it's the only reason that would explain the movie title, since that's the only thing the mom has in common with the grandma)
We are introduced to the weird looking daughter, who likes to chop dead pigeon's head (only one, not like she had a collection or something)
Weird daughter doesn't have friends, she sleeps in a tree-house for some reason, and has a couple of visions of her dead grandma (nothing really scary, just some kind of light that hints?
The son wants to go to a high-school party and mom forces him to take the daughter, you know, cuz she doesn't have friends and doesn't want his son to drink
Son doesn't drink but gets high, and the daughter eats some chocolate cake that creates an allergic reaction (daughter is allergic to peanuts)
Son, high af, rushes her to the hospital we guess, instead of calling 911. Daughter is choking in the back seat so she opens the window to breathe and, in a very "unpredictable" way, the son has to avoid a crash, accidentally making the girl lose her head against a pole (this one was a bit surprising, I thought the girl would have a bit more protagonism seeing the trailers)
Mom grieves her daughter and goes to a group therapy to cope with it, where she meets a nice lady who lost a son and a grandson
Said nice lady tells the mom she went to a medium and could talk to her grandson. She invites mom to her house and demonstrate that it is true (using a glass and a chalkboard)
Mom tries to contact the dead daughter, with her husband and son, and succeeds, but daughter's spirit seems to be kinda pissed (a glass is break during the medium session, so we guess)
Dunno if it's relevant, but mom sleep-walks, and we are told that once she woke up having his son covered in gas and her having a light up match in the past (ok?)
Son starts having hallucinations, not creepy ones (he sees himself into a glass smiling at himself. The most serious one has him half body paralyzed in his class and smashing his face on the table)
Mom hears sounds and goes to the attic, only to find a body, which she presumes to be the grandma (it has no head so we don't know). She asks her husband to go check it. Honestly the husband is the only real character we see in the movie "Why didn't you call the police?" he asks, and mom sets him on fire (?)
Previously, mom found a photo album of her mother (grandma) in which the nice lady who thought her to contact the death shows up (was she a ghost?, she knew her from before?, what were they up to?)
The only "mystery" is when the mom finds a page on one of grandma's books talking about "a demon who has to posses a male body", cuz the demon is male....)
After mom sets husband on fire, she goes after her son, who's still confused (as we all are I guess) of wtf is happening. He hides himself in the attic until mom appears hanging in front of him while stabbing herself to death
Son leaves the house and goes to the tree-house were the dead sister used to sleep. He finds himself with bodies with their heads covered up by bags, and a voice saying he's the incarnation of the demon they were waiting for (apparently, the dead sister was the first incarnation, but since she was female, she had to die)
Son, confused af, is being praised from the bodies, still with heads covered by bags, celebrating for the "incarnation"
Camera goes away showing the scene as if it is some kind of closure, and credits roll

Honestly, this is the longest review I ever wrote, but I feels that the disappointment I felt after watching this deserved it. Who in hell is saying this is the new "Excorcist"? It doesn't have the horror, the tension, the disturbing scenes (the most disturbing I saw was the 3 seconds of the dead sister's head on the road covered by ants, and it wasn't as disturbing as seeing the possessed girl using a crucifix on her "private parts", scene that still haunts me nowadays). Honestly, this movie tried to do a lot and didn't really delivered on anything. I guess that if a horror movie doesn't rely on jumpscares nowadays its supposed to be good, but this wasn't the case. I hope this review helps other viewers
