The boldness of The Workshop inheres, paradoxically, in its reluctance to sensationalize at stylistic or narrative levels, at least up to a point. . . . That said, the movie strands itself between its desire to provoke and its refusal of hyperbole, withholding coherent perspectives on the urgent subjects it broaches. A welcome demonstration of nerve becomes a failure of one, its psychosexual politics vaguer and smaller than its earlier, edgier scrum over civic values and intramural violence.
