Filmed with admirable restraint, this Spanish film makes its points with articulate ease. The pacing is effortless, sweeping the viewer along for the ride, keeping you on the edge of your seat yet sitting back just enough to let you get your breath. The quiet tension never overwhelms, putting you in the front seat of the main character's pursuit of justice. Kudos for not going with a Hollywood Liam Neeson revenge fantasy, this sophisticated movie is more interested in the complex and adult reality of this man's pain and determination. The only downside is a pivotal moment of stupidity by the main character which seems more like an artificial plot device than something an educated man would do, even in the heat of his uncovering of the truth about the fate of his son.
