This is a picture of the Yale Art Gallery.
To the right is the original building created in Italian Gothic style. To the left is an annex to the art gallery designed years later by Louis Kahn, who specialized in this post-modern crap. Yale administrators were initially perplexed as to why Kahn had designed a building that had nothing aesthetically in common with the current structure. They wanted to know why the only design feature was 3 horizontal lines on the outside. Kahn, being the fraud that he is, told them that he was revealing the floor levels that were hidden in the other building. The idiots at Yale bought this story and today the building still stands, a blight on the neighborhood it resides in.

Russia is still building communist blocks but "updated" with slightly improved exterior color. You'll see new blocks on both sides of railtrack from Moscow airport to the center. Miles, miles of deppressingly ugly buildings.
If you ask normal men what building they like most, they always name some classical ones. (I do too). But if you ask some architects than they very often will tell you some of this modern stuff. Maybe because they were trained to do something similar. But I am not sure.
