The newly expanded home of New York’s Museum of Modern Art (all of it) is finally open to the public, and Nicolai Ouroussoff says that the last of the newly built spaces is “unlikely to appease those who feel the museum has become a soulless corporate machine. But at least it underscores what is most alluring about the museum’s recent expansion… Seen from the street or the garden, the museum presents a continuous pattern of activity, reaffirming its public mission.”
