I find it surprising how little thought architects seem to give to how their buildings age. One feature you can find in many of these sort of dystopian cityscapes is rainwater marks below windows that make the buildings seem to cry. I can't believe that in this day and age we are unable to prevent that sort of thing by using the right materials or by directing rainwater to some sort of drain.
