“Sins In The Family” (** out of four) was a plastic suspense thriller about a happily married couple (Moniqua Plante and Jay Hindle) who are dedicated and devoted to their daughter (Natalie Sharp); however when her school guidance counselor (Meghan Heffern) begins to develop an unusual interest in her, they begin to suspect there might be much more lurking underneath her helpful demeanor. By-the-numbers thriller should be called AKA “The Guidance Counselor From Hell” but that probably makes this sound more fun than it really is. Competently made and acted but commits numerous “sins” of its own of silliness and unoriginality.
