Marlene Dumas is one of the two or three most successful female artists alive, if you judge by prices. I've never reviewed her work, because I find nothing in it to get excited about no matter how hard I look.

Being critical of art is a way of showing art respect. No sports writer would say, "Well the Yankees had a great season this year." No food critic would get a bad meal and say, "Oh, it was so lovely." It always strikes me as odd when people say, "Why do you write negatively about any art?" I think that everybody has mixed feelings about everything - even Goya. I mean, I look at Rembrandt sometimes and I hear a voice in my head go, "It's pretty brown."

Make an enemy of jealousy and envy. As fast and soon as you can…. The art world is high school with money.

I also take pleasure in the so-called negative power in Grotjahn's work. That is, I love his paintings for what they are not. Unlike much art of the past decade, Grotjahn isn't simply working from a prescribed checklist of academically acceptable, curator-approved 'isms' and twists.

The last time money left the art world, intrepid types maxed out their credit cards and opened galleries, and a few of them have become the best in the world.

I don't want to hear at all what the artist thinks about his art. And I'm not writing for the artist. I'm writing for the reader, and I want to tell the reader what I think.

Those who love him love that he sells the most art; they take it as a point of faith that this proves Kinkade is the best. But his fans don't only rely on this supply-and-demand justification. They go back to values.
