The title describes the services offered by a high-end Manhattan escort played by a sleepy porn star, Sasha Grey, in her aboveground debut. Those subterranean credentials should not lead you to expect any special degree of explicitness in the sexual activity, of which there is next to none. There is, meanwhile, a parade of clients and business associates and, for purposes of some superficial first-person narration, a recurring journalistic interviewer; and there’s a good deal of talk of economic angst against a backdrop of the 2008 presidential election; and there’s a bit of discord in the relationship with a nonpaying boyfriend. It’s all quite banal and clinical, a potentially interesting and challenging choice that fails to reach or approach its potential. The sum, from director Steven Soderbergh in his “indie” mode, is a digital doodle an hour and a quarter in length, gleamingly photographed, vapidly improvised, pointlessly nonlinear, parsimoniously informative.
