"I hope Michiko is polishing up her resume...."
That was exactly my thought after just a few lines in.
Actually the NYT likes to keep on staff a few contrarians, such as Kakutani. She is one of their prized writers. Note that she is attacking the work on the basis of its sloppiness and inauthenticity as art, rather than the truth or untruth of the content itself.
I would call this review devestating -it will be very influential in how the book is perceived by other reviewers.
