Charles Saatchi’s new show is jammed full of art. “An emporium is what it feels like – piled high, stacked deep. If one more work was tacked to one more inch of wood-panelled wall, the building would surely collapse. The central pantheon that guarantees the box office remains more or less intact: the shark, the dung, Myra and the bloody head, dead dad and the famously unmade bed. But all the other rooms, halls and corridors are jammed. By my count, there are more than a hundred new works on display, plus several more classics from Saatchi’s collection. You get three shows for the price of a ticket.”
