Scavenger of Human Sorrow - Jozlyn’s Spooky Season Marathon rankings

I'm really struggling to rate this horror offering. I really loved the slow creep of the family going from hosts to menaces, all the little things adding up and the end is brutal. However, the victims had multiple opportunities to just leave and what was the point? I could buy they were just psychotic nuts, but where did the babysitter fit in? Overall, recommended, just wish things were a little clearer.
