Films about sex are often too easy or too arty. Steve McQueen's "Shame" is neither. It convinces through clever pace, grimy-glamourous NY esthetics, and open-ended tension.
You also get to see Michael Fassbender naked, which is slightly reminiscent of Christian Bale in American Psycho, but more gratuitous (in a good way).
