I'm trying to recall a movie I saw on netflix a couple years ago... Ok so the movie is about a man who kills an old lady, a middle aged lady, and kids and keeps their skeletons. He imagines the skeleton as his family and went on a long hunt to find the perfect daughter to kill and to pretend skeleton is his daughter. Years later a family moves in next door and becomes friendly with him but sees he is acting weird. The end of the movie the new family breaks in and tortures the guy that you find out took their daughter.. I think the psycho dude is john goodman but I maybe wrong and I believe the movie has family in the title.
