I don't understand what's wrong with it. Since when are parks anti-urban?
Nothing wrong with a park. However, that Atlanta illustration is of a COURTYARD, not a park. Where is any continuity with that to the city around it? It is a fortress bound by buildings. It is a campus courtyard. Notice the buildings are the walls to the park. How do people get there? That is the problem with Northpoint. The Rose Kennedy Greenway is integrated with the city. Post Office Square is integrated with the city. That place in Atlanta and North Point are courtyards and are not interwoven. They are beautiful to LOOK AT, however.
