The debut show, “Second Lives: Remixing the Ordinary,” is supposed to be about how artists reuse humble or unusual materials. There’s good work here, but much of what’s on view is actually more about obsession and repetition: a couch made out of 3,500 quarters, a necklace composed of 100 handgun triggers. The building, too, seems caught between wanting to be an object of decorative delectation and making an architectural statement.

Turns out Picasso's passion for uncertainty, mystery, and the thrill of life never ended.

Artistic qualities that once seemed undeniable don't seem so now. Sometimes these fluctuations are only fickleness of taste, momentary glitches in an artist's work, or an artist getting ahead of his audience (it took me ten years to catch up to Albert Oehlen). Other times, however, these problems mean there's something wrong with the art.

The very paradigm of revolution, of right versus wrong, good versus bad, is a relic with no bearing on the present. Yet artists, exhibitions, and curators valorize the sixties. People who wrote about these artists 30 years ago still write about them in the same ways, often for the same magazines.

John Baldessari, the 79-year-old conceptualist, has spent more than four decades making laconic, ironic conceptual art-about-art, both good and bad.

Contrary to popular opinion, things don't go stale particularly fast in the art world.

Many museums are drawing audiences with art that is ostensibly more entertaining than stuff that just sits and invites contemplation. Interactivity, gizmos, eating, hanging out, things that make noise - all are now the norm, often edging out much else.
