“The Willowbrook” (*1/2 out of four) was a lifeless horror thriller about a renowned health-and-wellness instructor (Jessica Bishop) who invites one of her clients (Erin Day) to recover from recent drug abuse and an overdose at her manor but the client soon realizes the dark and dangerous existence at the manor beneath its helpful facade. Beautiful cinematography is a major highlight throughout but unfortunately it’s window-dressing on an old frame as film is tediously derivative of “The Shining”, “The Stepford Wives”, and also “Flowers In The Attic.” Bishop was also one of films’ producers.
