Bests & Worsts Reviews from Amazon

I read a recent positive review in the NYT and was expecting much more. The writing isn't terribly compelling and most of the "hidden" designs are not really hidden. I suppose if you know very little about the world around you, or perhaps you've never lived in a city, some things would be new to you, but, for example, it's not a great insight to point out that there are safety boxes used by firemen at most building entrances, or that cell phone towers are sometimes disguised as trees, or that some older brick buildings have been retrofitted with anchor plates to reinforce the walls. I would have liked a few pictures rather than the not very inspired drawings as well. Really not sure where all these five star reviews are coming from.
