I have finished A Little Hatred and The Trouble with Peace. I am starting The Wisdom of Crowds now.

I do not like them as much as the original trilogy. I feel he went too far with the humour and made it feel like a parody world rather than a real one.
He had the balance right in the original ones. Now it has slipped. Doesn't feel real any more. The new characters lack the weight of the original ones.
