Just plain dumb... . When I saw this in the library, I guess I was expecting another version of The Nanny Diaries, which was cute. This "novel," however, was poorly written and jumped all over the place; there were no smooth transitions at all. It was basically one big promo of her company--any time she mentioned a "horror story" she was quick to add that it wasn't one of HER nannies. Basically, I thought it was boring and that the writing style emulated that of the 3rd graders I teach. It took me about an hour to read, after which I thought, "How did THAT get published?" If you want to read a nanny book, try the Nanny Diaries. This book is stupid.

Ex Output:
NEG

Complete and Utter Fluff . There's no spark whatsoever in Spark. If you're interested in the subject of co-creation read Eric von Hippel's Democratizing Innovation instead.

NEG

Keeps on ticking............... . I bought and read this book many years ago and found it very helpful. I read it again a few weeks ago and was again able to appreciate it's value. Aside from the dated research, and some of the debate regarding the use of anti-depressants, it remains as fresh and powerful and relevant today as it was when it was published. It is definitely a giant step in taking the mystery out of depression and I would recommend it to anyone who wishes to learn more about the nature and treatment of this illness

Ex Output:

POS
