God of Carnage is another of those Yasmina Reza plays that, translated by Christopher Hampton and directed by Matthew Warchus, have become a kind of commercial-theater tic since the team's big success with Art, which at the time looked like a fresh twist on boulevard entertainment. But now, after three or four trips through Reza's sensibility, we know the pattern too well. A premise that generalizes about human beings is started, a counter-premise contradicts it, an attempt at synthesis upsets the apple cart, and back and forth the dramatic ping-pong ball goes. Reza is clever—exceptionally clever, this time around—at inventing little distractions to conceal the pattern from those who don't cotton on quickly, but these sidebars never deepen the basic premise or materially advance the narrative. Human beings are either A or B or an ungainly combination of both, and for her, that's really all there is to it.
