Jeffry Cudlin has a really eloquent and intelligent review of the Jim Dine show at the NGA in the current edition of the Washington City Paper.  Go get a copy of the WCP and read it or read it online here.

Here is a really intelligent and elegantly written observation (in my opinion):

"But one begins to sense a failure of nerve, a need to apologize for indulgences. In Owl, Rome (1997), swirls and puddles of shellac mixed with sand saturate the paper and stain it a range of dull ochres. A crumpled rag of the same color is glued to the upper third of the longish sheet of paper. Both this brazen non sequitur and the chaotic vigorousness of Dine’s treatment of the owl’s body feel like a guilty justification for the comparatively precious head sitting predictably atop it."
