The first half is creepy indeed. The neighbor, his garden with overgrown plants and the dead bodies in plastic. But then everything becomes clear that the neighbor turns his victims into obedient zombies with some drugs and nothing is explained further. It's some miraculous drug and it makes them kill for you and be there for you. The bodies in plastic looks really creepy and so is the little town. He formed another family with his new neighbors and the detective shot him when he asked him to shoot his dog so apparently the drug didn't work on him. No explanation as to why or how he achieves all these things.
