- Severe
- A girls deformed sister always looks and acts very frightening a lot and might frighten most viewers.
- There are some spooky scenic shots throughout, including a large burial ground atop a cliff, a makeshift cemetery for pets constructed by children, a woman hitchhiking in the dark next to an area of open forest, and a scene of tall trees falling over in the fog.
- There are multiple scenes where characters are visibly distraught, including a truck driver desperately trying to swerve around a child in the road (his panicking face is briefly shown), and a little girl screaming that her older sister is dead repeatedly as bizarre, hazy visions of other young children are shown onscreen.
- Pet Semetary is incredibly disturbing, vicious, and frightening. It is very depressing also.
- There is a scene in which a dying girl is shown, and her sister has visions of her coming to get her.
- A very disturbing scene in which the cat is killed by being held by the scruff of the neck as a syringe is injected into it's rear might upset some viewers as it slowly dies.
- The end is where you will probably get frightened.
- The premise of the film is very disturbing and frightening.
- When Pascow shows up, it is very eerie and frightening.
- Louis becomes mentally unhinged at the death of his infant son. His behaviour and mannerisms may frighten some viewers. Chilling fiddle music plays while he laughs at not being caught digging up his son's grave by the cops. He also burns a property down, shouts at a deceased cat and talks to himself.
- Near the end of the movie, there is a killer child that was brought back from the dead.
- The scene where a little boy is killed by an oncoming truck might upset and emotionally disturb some viewers.
