The film deals with extremely dark and disturbing themes. Many scenes portray this through bone-chilling high pitched music or terrifying visuals. Certain scenes are hard to watch purely for these reasons.
The subject matter concerns a son being convinced/manipulated by his father into helping kill his own mother. The murder and the aftermath, in which the traumatized teenaged boy comes to term with what he has done, can be very emotional and hard to watch.
Several animal deaths and injuries, including a couple of bloody and disturbing closeup sequences.
