When the first Paranormal Activity film was released in 2007 it breathed new life into horror and reinvigorated both the found footage and haunted house subgenres. As it became a franchise, however, the movies lost their edge and authenticity in many ways. After Paranormal Activity: Ghost Dimension was released in 2015, people thought that was the end. It was marketed as the last Paranormal Activity movie and there wasn't talk of another one for quite a while.
