Although the marketing hype is clearly trying to push this French-language Canadian production as yet another torture-porn horror movie in the 'Saw' vein, this is actually a very somber and realistic story about loss, forgiveness and revenge, although one which features a lot more graphic violence and gore than, say, Death Wish.
The basic premise is straightforward: Claude Legault plays Bruno Hamel, a successful Canadian surgeon who suffers a devastating family loss at the hands of a child molester and decides to personally administer his special brand of justice by kidnapping the perpetrator, transporting him to a remote location and torturing him over the course of 7 days while keeping him alive with his medical skills and equipment.
Most of the tension, and the most interesting aspect of the film, comes from the contrast between the main character's actions and his motivation. Will he be caught by the police before he has a chance to complete his plan? Will he give himself up or will he kill his prisoner? The extremely gruesome nature of Bruno's vendetta doesn't help the audience pick a side: we sympathize with his plight and want him to get away with it, but the violence keeps us at arm's length and prevents us from fully identifying with him.
I won't spoil the plot, but the film manages to remain engaging, though not exactly fast-paced, for most of the running time, thanks to a couple of plot detours along the way (including the involvement of another victimized parent). The graphic violence is strong and definitely goes for realism rather than being a showcase for ingenious effects (no fancy "death machines" and flashy editing a la "Saw"). Fun for the whole family this ain't!
Too graphic and explicit for mainstream audiences, and not flashy and 'entertaining' enough for the horror fan crowd, it's clear why the film bypassed theaters entirely in the US and went straight to DVD. Ultimately, the story is a bit too derivative to offer real surprises for anyone who has seen more than a few films of this kind, and the tone is so bleak and downbeat that very few people will pick this as their evening's source entertainment. But if you are looking for a serious and very explicit/graphic revenge thriller, this is a good candidate.
