Let it first be said: Philip Roth is a genius. His writing is astounding, both for its gorgeous display of language and, just as important, for its truth of character and humanity corruption.
"I Married A Communist", the second in the author's trilogy about the huge political movements shaping post-WWII American history (Vietnam, McCarthyism and, with his latest, "The Human Stain", the Clinton era and p.c.-ness), is a very, very good book. However, "American Pastoral" it ain't.
In this second volume, Roth tells the story of Iron Rinn, a militantly naiive political figure of the post-war generation. The themes are typically Rothian: definitions of success, alienation, what it means to belong, what it means to separate. And, while the plot is fascinating and there are portions of the book that are written so magnificently you'll want to weep, there is a remote quality --- a third-person-ness and therefore an aloofness --- that detracts from the overall effectiveness.
Still, the book deserves four stars because it's part of the Roth canon. He's always worth reading and always astounding and delightful and depressing and devastating. Even when he's merely being a bit more mortal than we've come to expect of a writer with his gifts.
