Of course such things are extremely subjective. One thing I have noticed that bothers me with new developments are trees. They are always short, because they are still young. Hence they have no character, yet. Storms haven't ripped them, they haven't been shared when they cover someone's window from sunlight. And if course they are always perfectly aligned and usually rounded with a square made of tiles. Everything measured and inch perfect.
Interestingly this bothers me with new developments, that everything is too neat and measured. At some places I appreciate it.
