Obviously, the studio had no intention to improve on the original, just up the suggestiveness & violence, give it a modern look and film it with a new cast & director. The aim, of course, is simply to target a teen audience that settles for anything that has suspense, terror, bloody violence, a sexy teen couple & updated morality
A troubled son (Penn Badgley, who seems badly directed for his role) returns home from military school to find his mother in love with, and sleeping with, the man who is to become his stepfather (Dylan Walsh, who carries his role well with devilish split sweet/evil personality). His mother (Sela Ward, appearing sympathetically earnest as the divorcée cum new wife) radiates with a renewed look on life and with dreams of a happy family once again. Balancing out the foursome is the son's lifelong girlfriend (Amber Heard, whose basic talent is skin deep, well tanned).
For the target audience, there are shock moments to stop the heartbeat momentarily & plenty of skin showing between the younger leads. For the rest of us, it's hardly enough, 90-minutes of on-again, off-again schlock terror. (Grade: C-)
