warn represent may contain spoiler my huge problem with this movie be how totally self center and self consume the adulteress wife be . after have a one night stand with a slimy psycho she be be stalk by him . he call her constantly and threaten her and even send a video of their night together . he be obviously crazy and very dangerous . the problem be she only think he be dangerous to her ( and expose her secret ) . not for one second do she ever have one thought of concern for her husband . do she even for a moment think of him possibly be in danger from this psychotic . as soon a she realize how mental he be she should have warn her husband no matter what the consequence . maybe there wouldn not have be a movie then but there really wasn not one anyway so what the difference .
