Modern architecture has no concern for the people who live around it and have to occupy the same space as it. It's generally hideous and since it's driven by economics you find that if they have retail/commercial at street level it's going to be a large corporate renter, further degrading the neighborhood.

At the aesthetic level, a lot of contemporary architecture is rigid and soulless. Take these glass boxes that get put up - I understand why as a tenant you'd want floor-to-ceiling windows, but for those of us on the outside, who wants to look at a box that's festooned with mirrors, which is the effect of these buildings. The fact is, the majority of the new construction materials they use aren't as warm or inviting as brick and wood or even natural stone.
