The Terractotta Warriors, Darwin, Cranach, Blake, Byzantium and Babylon (the latter fully booked!). Blockbuster exhibitions have huge visitor figures. High visitor figures are a measure of success.
But looking at the exhibits includes new experiences; not being able to linger too long on a object as someone else is hovering in wait, even jostling, for the prime position. Crowds are reflected in the protective glass. At last, you are propelled out of the exhibition and straight into the gift shop.
