Primarily, this is a thriller that delves into the realms of seismology, big corporations, and Christian fundamentalists. However, it also weaves in one or two love stories and presents various dysfunctional family relationships, along with some amusing subplots. I believe its main shortcoming lies in pandering to the American penchant for convenient endings. On a more minor note, as a British reader, some of the characters' names are initially rather misleading as they deviate so far from the stereotype associated with that name, especially Eileen.
Nevertheless, it remains a good story, featuring some wonderful writing. At times, though, Franzen's self-indulgent riffs can be excessive. The oddest instance is a three-page description of the daily life of an anthropomorphised raccoon. This rather unexpected detour can seem out of place and perhaps a bit too self-indulgent on the part of the author. Despite these flaws, the overall story still manages to engage and hold the reader's attention, with its interesting blend of different elements and themes.
While I am always deeply impressed with Franzen's remarkable intellect and outstanding skill as a writer, I find myself growing increasingly weary of the cynicism that pervades his characters. This cynicism often has a dual effect on me, alternately making me loathe the characters or leading me to believe that Franzen himself does. I do, however, truly appreciate his masterful and layered character development. He has the courage to write characters that are far from perfect, that are 'messy' in their thoughts and actions, giving a voice to the less than saintly aspects of our own lives. Nevertheless, so many of Franzen's characters seem to fall into certain unappealing categories. Many of the men appear to be deeply narcissistic and inherently miserable, while the women often come across as either pathetic or one-dimensional. His female characters typically read as either shallow and materialistic, vindictive, or deeply needy and overly dependent on the men in his stories. Yet, as was the case with his other books, even as I found myself balking at some of these characterizations, I remained completely engrossed in the story. I simply had to finish what I had started. So, go figure.
