Like it or not, you can’t have a serious discourse about an art form until you have people whose sole involvement in that art form is criticism. You need, in effect, an independent press. Actually, to be clear, what you need is an economic model that can support a corps of passionate, clear-thinking individuals who are dedicated to vigilantly watching over the progression of the medium. Recent troubles aside, this is why art, film and architecture have achieved such great heights in our society: those art forms are economically robust enough to support a vibrant critical class.
