5. Maurizio Cattelan: All
Dates: November 4, 2011 to January 22, 2012
Known as a prankster, Maurizio Cattelan doesn't disappoint with his career retrospective at the Guggenheim. More spectacle than anything else, All finds each of the assembled works hung miraculously in the building's famed rotunda. Lines have sprung around the block. Simply put, in a year of long art lines, this is the one most worth waiting in.
