This horror prequel depicts the events that lead to the massacre of a family. The movie was based on the actual family who lived in the Amityville house, the DeFeo's, who were all murdered by the oldest son. There are inaccuracies to not only the real events, but to the events depicted in the first movie. I remember being told this movie was "scarier than the first one," but I found myself laughing at most of it. Don't get me wrong, there were still some creepy moments (the mother feeling a presence in the basement, Sonny being attacked by the presence and hearing the voices), but it was mainly made up of bad writing and awkward dialog. Some of the special effects were surprisingly done very well for their time. Jack Magner also did an exceptional job portraying a young man slowly losing his mind to a maleficent force. It was decent, even with the bad dialog, until the last twenty minutes or so. The ending was very weak and fell flat. But overall, I would say to watch it for the good parts I mentioned and then make fun of the rest.
