To start with it is a movie.
Second it is a horror movie.
Third it is a low budget horror movie that aspires to the grade “b”.
According to IMDB, the same person is the writer, director, producer, editor, cinematographer and caterer.
There is no credit for “researcher”.
OK so I lied about him being the caterer.
Horror movies that claim to be based on a “true story” never are.
