Thia is the saddest story I have ever read! Poor girl---she doesn't have a chance with finding a happy life! The cards are all stacked against her from the git-go!

Ex Output:
Negative


Ex Input:
I was expecting to read a book about the Amish. What I read instead was a very self centered book about a woman searching, rather blindly, I felt, for herself.She had very little in the way of insight into Amish life, even after spending a period of time with them. And her inability to get outside of her own head/her own life was not terribly interesting to read.For someone who always longed to be a 'star,' I am sure publishing a book was quite a thrill for her. Shame she used the Amish as a platform for her own ego.

Ex Output:
Negative


Ex Input:
I read this book and concluded that I am angry at myself for having read it. Pilots like to read about accidents hoping to study a case and avoid the same mistakes. After wasting your time with worthless and mediocre family stories and the well known government incompetence, you end up with the empty conclusion that a good pilot, in good health, all current and confident ditched in the stormy ocean at night and disappeared. None of the worthless stories or ILS text in this book provides any conclusion or lesson to be learned. A line from Billy Madison comes to mind: "you are now all dumber after hearing this story". In fact the only intelligent thought comes from an opinion of a reader that raises the theory that Ron S. used a GPS approach rather than ILS and that proved fatal.
