As an entry into the 'decent family menaced by kidnapper' canon, this is a well acted psychological thriller. Brosnan, Butler and Bello are the focus of the movie, other actors providing little more than cameos. Pierce Brosnan's character provides the requisite menace without resorting to eye-rolling psychopath, while Maria Bello and Gerard Butler are an effective couple-on-the-edge. Any more of the plot will give too much away but this is a largely character-driven film, the tension coming from the performances rather than any crash bang action sequences.
The story moves along quickly and effectively and probably suits the small screen better than the cinema. It's one of those thrillers where knowing the ending will probably reduce the number of repeat viewings though, unlike something like The Sixth Sense where the journey was as much fun as the destination, in this case there are few stand-out scenes to re-enjoy.
Much of the film takes part at night and the Blu-ray retains good shadow detail. Picture quality is generally good but this isn't the type of film to marvel at scenery or SFX so would be just as enjoyable on DVD.
