[This is a review of the film, not the Blu-Ray itself, which has not yet been released.]
A beautifully shot, deliberately paced existentialist meditation on crime, relationships, and truth. Shot mostly in gorgeous long takes that take full advantage of the widescreen aspect ratio, the film requires (and rewards) patient viewing. The first half of the film, in which a late-night caravan of law enforcement officials drive two murder suspects to a series of nearly identical rural wells, looking for the location of a buried body, is brilliant. It echoes Waiting for Godot, as the seemingly endless search for the body fades into the background, and the focus turns to conversations about personal problems, petty bureaucracy, differing values, and the meaning of life. As the film continues, different members of the caravan wax and wane in importance, each offering a different perspective on life and one's place in the world. The final act of the film -- which occurs back in town the following day -- drags a bit, but contains powerful revelations.
Despite it's subtle metaphysical explorations, this film is also a highly realistic police procedural. It is very faint praise to say that this film is the anti-CSI, but it's cynical views of truth and justice contrast starkly with TV procedurals. A vain prosecutor basks in his role and makes up facts for convenience, no one has remembered to bring a body bag (or a hearse) for the corpse, the gendarmes are more concerned about where municipal boundaries fall than anything else, a critical medical discovery is fudged, there are rumors the murder victim has been seen alive in neighboring towns, and nothing is wrapped up in an hour, let alone 150 minutes...
This is a film for patient viewers who enjoy the liesurely-paced works of Malick, von Trier, Kiarostami, Tarkovsky or other auteurs of so-called Contemporary Contemplative Cinema.
