Poorly done non-descriptions are as annoying as poorly done descriptions.

Absolutely. I guess if you're used to one you might notice the flaws in the other more obviously, but it's a shame that descriptive writing sometimes gets used as a synonym for boring as if it always stops the story dead. With some writers it's all intertwined. There's a special feeling you get from writers who can paint you into a world so well. It perhaps does usually come with a different pace--but that pace isn't always slow in retrospect. I find myself thinking of We Have Always Lived In The Castle, which I think of as very descriptive--and it's just delicious!
