“The Good Nanny” (** out of four) was a plodding and predictable thriller about a strong-willed nanny (Briana Evigan) who takes a job at a luxurious estate taking care of a beautiful young girl (Sophie Guest) but she soon comes to realize that things aren’t quite right with her parents (Peter Porte and Ellen Hollman) and she attempts to uncover the mystery of what’s really going on. Attractively shot and competently acted but offers little in the way of surprises or thrills and seems to be following a much-too-familiar format. Tatyana Ali has a key supporting role but you wonder whether all these direct-to-tv movies are “good” for her career or not.
