Depthlessness is the supreme formal feature of all postmodernisms.

Evidence

But there are some other significant differences between the highmodernist and the postmodernist moment, between the shoes of Van Gogh and the shoes of Andy Warhol, on which we must now very briefly dwell. The first and most evident is the emergence of a new kind of flatness or depthlessness, a new kind of superficiality in the most literal sense, perhaps the supreme formal feature of all the Postmodernisms to which we will have occasion to return in a number of other contexts. — Fredric Jameson, Postmodernism, or, The Cultural Logic…, 55
