Query: Embarrassingly shallow

I am not a historian. I am someone who reads history and who has a great deal of respect and admiration for Japan, its society, and its complexity. I bought this book before boarding a long flight and looked forward to learning more about the Imperial dynasty and its role in the great historical dramas. Instead, I spent my time reading a largely unsubstantiated attack. Even allowing for the author's rather extreme point of view, I found the book embarrassingly shallow, mean, and totally one-sided. Other than a few vignettes about some of the members of this mysterious and underreported family, this book offers little.
