What a fabulous edge of the seat, nail biting thriller! Even though it reminded me of Single White Female in its very dark and menacing undertones, I felt this was an excellent film.
A held together Heigl plays an ex who feels she deserves another chance and, beneath her benign and friendly exterior, lies a malicious woman, determined to get her family back.
Dawson, the soon to be new wife, is the only one shown this side of Heigl, and her fiance refuses to believe the truth until it is almost too late.
As a writer, this film took me back to the days of Hitchcock and highlighted the power of suggestion – showing the audience things the characters do not know, making them root for the characters. This creates suspense and this is critical to a thriller.
