Koons's work has always stood apart for its one-at-a-time perfection, epic theatricality, a corrupted, almost sick drive for purification, and an obsession with traditional artistic values.

First let me report that the art in the Barnes Collection has never looked better. My trips to the old Barnes were always amazing, but except on the sunniest days, you could barely see the art. The building always felt pushed beyond its capacity.

Too many younger artists, critics, and curators are fetishizing the sixties, transforming the period into a deformed cult, a fantasy religion, a hip brand, and a crippling disease.

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.

Many things happened in the sixties, but the period is no more significant, better, or more 'political' than today. It's time to turn the page.

Galleries began growing in both number and size in the late seventies, when artists who worked in lofts wanted to exhibit their work in spaces similar to the ones the art was made in.

Once artists are expected to shock, it's that much harder for them to do so.
