Well, i went to go check out the Amityville Horror movie. Not bad, but Hollywood altered the truth of the story. Since I live four miles from the actual house, I decided to take a drive past it today to check it out. WOW! The house has changed since 1974. You wouldn't even recognize it. The current owner has done renovation since he has been there, especially to the boat house.
You can catch some truth behind the story here and here.
