Usualy the wiki wouldn't include such titles, but this appeared on the credits of Amityville: an Origin Story, so it gets an exception.
The 3 hour installment has like 15 minutes of story-footage, which contains surprisingly well placed jokes and a backstroy why the house is haunted. Even more surprisingly Jodie the Demon Pig from the poster appears in the movie. The title-character on the other hand only mentioned once, though that barely takes away from the experience.
On facebook @The Amityville Saga made a sex-less fan-edit for the completionists who are only interrested in the story of this spoof.
