Being a fan of authentic Dada, I find today's art - what I call 'Bankers' Dada' - mind-numbingly dull. The most challenging work I've seen of late is by The British Art Resistance. Their document, 'A Call for Heroes in an Age of Cowards', is apt in these days of witless chancers.
The work itself is the reward, and if I choose challenging work, it'll pay me back with interest. At least I'll be interested, even if nobody else is.
