Hornby does a great job of displaying the mental gymnastics that settled, comfortable people can perform while trying to figure out what it means to be happy. Although not in an altogether pleasant way as Hornby is definitely skewering those who have enough time to induldge in bourgeois, self-centered concerns while at the same time recognizing that they are valid, tricky emotions that a lot of people wrestle with. Doesn't paint a very flattering picture but it certainly is a real one-- it dares to be honest and bluntly addresses the fact that many of us behave in ways that don't even make sense to us or what we believe. That most people are hypocrites, even those who devote themselves to trying not to be.As for many of the negative reviews, I think you have to be able to relate to the subject matter to enjoy it-- meaning if you are (or have been) married for a long time then the book makes a lot of sense, even in a somewhat painful way.
