Years later, the two cross paths again, and Michael (played as an adult by Ralph Fiennes) learns, slowly, horrifyingly, of acts that Hanna may have been involved in during the war. There is a war crimes trial, and the accused at one point asks the panel of prosecutors: "Well, what would you have done?" It is that question--as one German professor says later: "How can the next generation of Germans come to terms with the Holocaust?"--that is both heartbreaking and unanswerable. Winslet plays every shade of gray in her portrayal of Hanna, and Fiennes is riveting as the man who must rewrite history--his own and his country's--as he learns daily, hourly, of deeds that defy categorization, and morality. "No matter how much washing and scrubbing," one character says matter of factly, "some sins don't wash away."The Reader(with nods to similar films likeSophie's ChoiceandThe English Patientdares to present that unnerving premise, without offering an easy solution. --A.T.

Going down the final stretch--and Samantha's cancer--gives the series a more serious tone, but there's always a jab to tickle the funny bone: Miranda's awkwardness with happiness, Charlotte's latest passion, Carrie typing someplace new, and Samantha getting into Paris Hilton territory. Like any series winding down, there is a wedding, a baby, old faces popping up, and some star-ladened new ones (like creative consultant Julia Sweeney as a nun). In the final two-part episode, "An American in Paris," Carrie faces her romantic destiny, but also solidifies herself as a fashion icon, an Audrey Hepburn for 21st-century television. In the penultimate episode, she asks her friends an emotional question: "What if I never met you?" Certainly fans can ask of themselves the same question and reminisce how much better TV became since they first tuned in these four women of the City.

Gottman, the director of the Gottman Institute, has found through studying hundreds of couples in his "love lab" that it only takes five minutes for him to predict--with 91 percent accuracy--which couples will eventually divorce. He shares the four not-so-obvious signs of a troubled relationship that he looks for, using sometimes amusing passages from his sessions with married couples. (One standout is Rory, the pediatrician who didn't know the name of the family dog because he spent so much time at work.)

Gottman debunks many myths about divorce (primary among them that affairs are at the root of most splits). He also reveals surprising facts about couples who stay together. Theydoengage in screaming matches. And they certainly don't resolve every problem. "Take Allan and Betty," he writes. "When Allan gets annoyed at Betty, he turns on ESPN. When Betty is upset with him, she heads for the mall. Then they regroup and go on as if nothing's happened. Never in forty-five years of marriage have they sat down to have a 'dialogue' about their relationship." While this may sound like a couple in trouble, Gottman found that they pass the love-lab tests and say honestly that "they are both very satisfied with their relationship and they love each other deeply."
