For the first hour or so of HBO's two-night documentary event, The Zen Diaries of Garry Shandling, you'd be forgiven for assuming the key word in that title is Diaries. In a brief opening, Shandling himself, who died almost exactly two years ago now, shows the diaries he kept all his life to the camera, and reads a particularly banal passage.
He grins. Or maybe he winces. It's a little of both, really. And there it is: That pained smile was the patch of comedy real-estate Shandling staked out for himself, and still owns.
