This essay compares the horror films Paranormal Activity and Insidious. Both films involve paranormal activity in a family's house centered around threats to the parents' children. Specifically, the films feature demons haunting the families - in Paranormal Activity it is a demon summoned to protect the family that ends up terrorizing them, while in Insidious it is a demon that kidnaps the son's soul. Though the endings differ, with only Insidious having a happy conclusion, the essays argues the films have notable similarities in their premises, supernatural elements, and threats to children that make them effectively comparable within the horror genre.
