This wasn't a bad film, it was entertaining, made you guess most of the time, and was pretty tense, its only flaw is some stupidity, and the jump scenes in it are predictable. Plus the film itself is predictable, but it is good, and it worth watching. Halle Berry is sensational as The Rich Man's Wife. The ending is especially satisfying, making your jaw drop to the ground. I give it a 7 out of 10. Rated R for strong violence and language.
