Example Input: Good idea didn't translate into a book . I like the idea that Michael Lewis wrote this book/article to defend a man whose coaching techniques are clearly out of style in todays world of my child this and my child that. Having said that I did not like this book:    1) the writing was chopping and hard to follow at times. i had to re-read many sentences to understand lewis' point.     2) the story lacked the depth of lewis' other wonderful books - where's the who/why/what that lewis used to moneyball (and others) educational - i wanted the story behind the story.     3) who were all the pictures of? i found them distracting...     i'll continue to read lewis' books bu thope the next one is bette
Example Output: NEG

Example Input: Disjointed Narrative . I had originally seen this book as a subject of PBS' Frontline several months ago. I was enthralled by the subject matter and decided to get a copy from the local library and read about it myself. What a mistake. The PBS Frontline TV program was so much better than the book. I found Maraniss'  switch from the Viet Nam story to the University of Wisconsin protest story very aggravating; and, as another reader mention, it made for a very disjointed narrative. The juxtapositioning of the two narratives does not work!    I found myself more interested in the war portion of the book than reading about Soglin and his friends embroiled in a protest against Dow Chemical. Frankly, I found this portion of the book to be quite a bore and it almost ruined the book for me. Who cares about college kids and their protesting episodes. It is simply not important.     If you are interested in reading the book, read the Nam portion and skip the protest chapters. Better yet, catch the Frontline episode and skip the book completely.
Example Output: NEG
