Generally, the acting proves spotty. Possibly that thudding, bass-heavy sound design by Brandon Keith Bulls, icy music by David T. Little and an intermittent yellowish atmospheric haze undermines performances. A less than charismatic McKinley Belcher III is a handsome though mostly stolid Coriolanus; speaking the blank verse, he tends to hit the cadences hard. The greater disappointment is the director’s slack, unimaginative shaping of the crucial scenes involving those so-swayable Roman people, who collectively become the drama’s motivating force. Clad in East Village mufti, they’re noisy but scarcely suggest a dangerous Roman mob. Perhaps it would have been wiser to invest more in additional actors and their rehearsal than in tech.
