What does the Mona Lisa do for you?

The other day I was listening to Moscow radio when I heard an interview with some artist who was causing quite a stir when he said on national TV that Mona Lisa did nothing for him. He went on to expound that he was really upset about the way people are told that they have to appreciate "great" art, music, whatever. At some point, the peer pressure to call Picasso or Leonardo a great artist at some point turns people into zombies, who are unable to think for themselves.

Sometimes I wonder if the same happens in the Rabbinical world, although it is not a unique phenomenon.
