When you have wasted space in a city with massive rent increase, then yes, it's horror. The land could be easily used to create new park areas, stores, or housing units. Instead you have absolutely nothing other than waste accumulating.

Well, either you build over the growing plants in the city, or you raze plants in the outskirts. The former gets complaints because people want greenery in the city, the latter gets complaints because of sprawl, added traffic and unnecessary pollution.
