Resolve it in Flatness

It seems to me that one of the predominate legacies of Modern Art has been 'flatness' meaning the tendency of artists to abstract/remove pictorial space & depth. This seems to have carried over in a lot of today's artwork which on the surface? seems figurative but is actually quite flat, lots of painting from photographs have this what I like to call the 'painting by numbers' look, reducing everything to an outline and then filling it in.. take Peter Doig for example. I do like his art and I think there is much more to his work, but there seems to be a bit too much of this stuff going around.
