Negative Dialectics

In Aesthetics with DKJ, we were discussing very briefly Theodor Adorno who, according to DKJ, comes up in almost every discipline and what interested me mostly (he interested me quite a bit otherwise) was what he put forth in his Negative Dialectics, a kind of critique of Hegel's dialectic in which there is not such a hopeful resolution into synthesis. I was wondering whether anyone knew anything more on this or has any notable anecdotes of experiences with Adorno.
