The concept is excellent and the 1st three episodes kept in line with where I thought this concept may go. But then it fell apart for me as non relevant characters were introduced but they never played the psychological roles I thought they were going to play(like the home inspector, the woman with the pig tails). It was full of a bunch of unbelievable horror stories about the previous happenings in and around the home, which really made no sense. In the end the only two things that made sense was that the private investigator lied about being the watcher because she did not want the family to live their lives in fear, and that the husband was the actual watcher, even though we r made to believe that the watcher was never revealed.
