This reconstruction doc. looked at the events surrounding American folklore's strangest murder mystery - investigating what really happened on the night Ronald DeFeo apparently gunned down his entire family, and examining the alleged haunting of the Amityville house for years afterwards.
Featuring exclusive interviews with George Lutz and many of the original participants in this story. There are some long pause breaks and some information may be wrong, but overall this documentary looked at both sides very well I thought.
