content: Since I tend to steer away from thrillers in general, I am not likely to say I've seen this plot before, which appears to be the major criticism provided by most of the posters. My spouse is a huge SB fan, and we are catching up on her movies that we somehow missed, or those we want to see again. Bullock is convincing and riveting as a damaged cop. The two young boys are absolutely chilling. Ben Chaplin is adequate. My major problem is with the police department's eagerness to wrap up the case, and the way Cassie's boss treats her when she is not satisfied with the way the case is initially closed. If she is so bad at her job that her boss won't even recognize her instincts, why does he even keep her on the force? I found his treatment to be demeaning and unrealistic. Other than that, this was a fine Bullock movie (certainly better than most of her "serious" efforts), and I would call it a worthy addition to the genre.
