I enjoyed the Watcher. Mia Farrow was so ethereally comical. The fact that the Couple purchasing the house continued living there upon finding about the horrific murders, was a must watch for me. For most, it's not that much love of a house in the World. All the actors were great & kept me glued for two days. The Realtor got exactly what she deserved in the end. Poor doggy didn't need to pay for her greed. Just loved the African female detective, who befriended the couple. That Woman was excellent information!!
Finally, I think Mia Farrow's challenged relative ( as hard as it is to believe) minus the letters was the WATCHER!!
