What a week for art! What a week for the wisdom of crowds! It’s just seven days since Channel 4 announced the premise of their latest intriguing/oh-so-interesting/irritating TV show. This time there are no obese people losing weight through the magic of trampoline or naked S&M potholers forced to live in an Orkney nunnery for a year. The idea this time is to buy works of art by “problematic” artists and then ask a studio audience if the pieces should be destroyed by the intriguing/oh-so-interesting/irritating Jimmy Carr. Who, after all, wouldn’t like the idea of consigning the work of Adolf Hitler to the wheelie bin of history? What about Rolf Harris? Eric Gill? And who is going to stand up and defend the art of the very worst people?
