Ex Input:
This book is not for everyone. It is extremely scary and disturbing. At the same time, it is a fascinating look at the police work and prosecution that brought the murderous Manson Family to justice. The book is hard to put down; the in depth discussion on presenting a criminal case in court and developing evidence to support the case is outstanding. The main complaint is that the book is a few hundred pages too long. The author seems a little too self-promoting, but then again he did get a prosecution on one of the biggest murders in history.

Ex Output:
Positive


Ex Input:
The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.

Ex Output:
Negative


Ex Input:
I think a couple of people are missing the point... The reason this is out is (I heard) they didn't have the cash to finish AV Vol 2, so this would generate some cash AND be of interest to their core fans. Plus, the demos ~are~ a good insight to their creative process.... I ~love~ to see the rough drafts... If you're just waiting for Vol 2, why did you buy this in the first place?

Ex Output:

Positive
