Gladwell's most enjoyable book so far . It is a feel-good extravaganza , nourishing both heart and mind . Each of its stories ... has an ending that is both happy and surprising . What ostensibly unites the stories are the twin ideas that an advantage can sometimes be a disadvantage and that a disadvantage can sometimes be an advantage . Yet there is something more powerful and more uplifting that also links them . It is good beats bad - just when you least expected it .
