Query: Not up to his usual standards

I guess because it is a collection of observations and not as focussed as his other books I lost interest in this one. Without a central theme other than "How strange America is now" Bryson's generally on target wit and observations tend to meander from point to point. Viewing America from the perspective of an American who had been away for years is definitely aimed at a British audience who I hope enjoyed it more than I did.
