Jim Van Bebber’s “The Manson Family” is an extremely violent and bloody horror film that reconstructs the early activities of the Family and their descent into the Tate-LaBianca killings. Van Bebber mixes this with a contemporary sub plot involving tabloid journalist Jack Wilson’s quest to film a documentary on the subject.The film is loaded with plenty of sex and full-frontal nudity. The final third of “The Manson Family” is a grueling nightmare with some of the most sadistic and savage murders ever captured on screen.
