The Last House on the Left was a morally bankrupt but highly profitable film about rape, murder, and revenge. The 1978 sequel, The New House on the Left, may even be more reprehensible than the original. Whereas the murder site of the first film was a remote house, the scene of the crime in the sequel is a train (thereby negating the title). This film includes more rapes, more murders, and more revenge than the original --and, undoubtedly, more cash lining the pockets of the producers.
