The film tagline was "No es una pelicula de terror, es de verdad". (This is not a horror movie, this is real)
Carlos Trejo apologized for the film and the book after the film was released.
Audiences criticed the film's takes and the camera's movements, they didn't let see nothing or sometimes made the audiences feel dizzy.
Based on the book with the same title by Carlos Trejo.
The film has received many negative reviews that many people consider the film a comedy rather a horror film.
