A tediously repetitive film desperately looking for some heart and soul. Reeves is the Man of Concrete, grey and predictable behind the camera and an impassive mask of grunts in front of it. Definitely no excellent adventure.
An adequate and ambitious effort from a first-time director who could have enhanced his on-screen philosophical arguments with a bit more depth and done with a touch less of the admittedly riveting man-to-man melee.
Cinematographer Elliot Davis films the fight scenes with thrilling immediacy: lots of long takes, so you realize you are actually seeing these guys actually do this, as opposed to watching something pieced together later in the editing room.
