The general tone and subject matter is quite disturbing.
There are a lot of intense and disturbing scenes of horror throughout.
A character has multiple PTSD inflicted panic attacks throughout the movie, clearly experiencing great pain and crying in an infantile way.
Numerous intense scenes of familial relationships falling apart. Emotionally draining and highly uncomfortable.
Besides the supernatural elements that get infused, the film is deeply about family loss and grief.
This movie's tone is quite dark and even if you don't believe in things like the paranormal, the feelings of loss and grief the characters experience are all too real and can scare just about anyone.
Hereditary is considered one of the scariest horror films, the movie doesn't scare you in a fun way it is very haunting.
MA15+ (Strong Horror Themes & Violence) very scary.
