Poison Ivy is a sinister and savvy psychodrama that is mesmerizing from start to finish. Drew Barrymore gives a riveting performance as a teenage outsider who decides to manipulate a wealthy family for her own benefit. She befriends the insecure adolescent daughter (Sara Gilbert), charms the sickly and suicidal mother (Cheryl Ladd), and then seduces the father (Tom Skerritt). This film directed by Katt Shea is one of the scariest portraits of a soul murderer since the classic 1968 film Pretty Poison starring Tuesday Weld.
