Jeff Koons on the Roof

Special exhibition at the Metropolitan Museum of Art through October 26.

Inside, the enormous shiny metal balloon dog might look overwhelming or creepy, but outside, underneath the vast blue sky on the Met’s roof garden, it’s charming and whimsical, a giant-child’s plaything. Even after all the trouble to get to the roof, even when the sun creates a glare on the lacquer, the sculpture feels utterly blithe. It makes me smile just to look at it.
