Chained

The nine year-old Tim (Evan Bird) goes to the movie theater with his mother Sarah (Julia Ormond) and his father Brad Fittler (Jake Weber) tells Sarah to take a cab to go home. After the session, Sarah and Tim take the cab of Bob (Vincent D'Onofrio) that abducts and bring them to his isolated house. Bob kills Sarah and shackles and gives rules to Tim, nicknaming him "Rabbit". Along the years, the psychopath serial-killer Bob keeps killing women and Tim cleans the house and the blood, buries the women and eats Bob's leftover. When Tim (Eamon Farren) grows up, Bob decides to treat him as his son and unchains him, but Tim is reluctant to accept him. One day, Bob brings the gorgeous teenager Angie (Conor Leslie) expecting that Tim has sex with her and kills her. What will Tim do with Angie?

"Chained" is a disturbing, twisted and depressing loss of innocence of a boy kidnapped by a sadistic and deranged serial-killer and with a surprising plot point in the end. Vincent D'Onofrio is a scary psychopath with a twisted mind. The fate of Angie is omitted in the movie and this is the weakest part of the cruel plot that makes an ambiguous conclusion. My vote is seven.
