Inside a darkened house looms a column of TVs littered with VHS tapes, a pagan shrine to forgotten analog gods. The screens crackle and pop endlessly with monochrome vistas of static white noise permeating the brain and fogging concentration. But you must fight the urge to relax: this is no mere movie night. Those obsolete spools contain more than just magnetic tape. They are imprinted with the very soul of evil.
This movie contains 67 potentially triggering events.
A dog is seen falling from a great height and is grievously wounded. This trash, unnecessary scene is put in for shock value and nothing more. Aren't enough animals cruelly murdered in real life? I see these movies for an escape. This actually drags down the film.
The main characters of the wraparound are private investigators who stalk and film a man in the beginning of the film to capture video evidence of him cheating on his wife.
In the frame story, an individual on a recording mentions a collection of tapes that were “mostly snuff and CP.” In this context, “CP” likely stands for “child pornography.” These tapes are not described any further, just mentioned in this one instance.
In the first VHS segment, an adult woman is apparently being followed by the ghost of her “creepy uncle.” This ghost is depicted as a middle-aged man in his underwear. At one point the woman tells another character that the uncle was “not a nice person” when he was alive. Abuse is never explicitly mentioned, but it is an easy conclusion to reach, especially for a viewer who might be sensitive to such things.
As other users have mentioned, in the third VHS segment, there is a reference to the cult leader abusing the children in the commune.
There are several graphic scenes of characters v* after being bitten by zombies. There is both build-up and audio. This happens a little before half-way into the movie on the second tape.
On the third tape, Lena retches and gags a bit, but does not v*.
Something that specifically got me was the third(?) tape (Indonesian) with the demon. At the end of the tape, there is a long string of bloody saliva dripping from his mouth and a LOT of mucus hanging from his nose.
