Roberta Smith says that the overwhelming success of London’s Tate Modern ought to give New Yorkers, who ponied up close to a billion dollars to build the new Museum of Modern Art, pause. “That MoMA could have spent so much money on a design that seems so unaccommodating — and already feels too small — for its growing audience is a travesty… The lessons of Tate Modern challenge a lot of conventional wisdom, at least that expressed in many American museums these days. Most important, Tate Modern’s huge building proves that being big is not the same as being corporate: it is possible to have a large institution feel personal to its visitors.”
