Example Input: On a number of occasions, it had been suggested that I read this book, and I must say I'm very glad I did. I got very involved, as the writing was so wonderfully descriptive. Having said this, I don't think it was arduous to read all that detail, which sometimes makes reading a book feel a bit of a chore. I would recommend it to anyone!
Example Output: Positive

Example Input: 'The most dangerous man alive'? Doubtful...more like an individual who proves how influential environment is on forming of human character. If you read this book and don't in some small way sympathize with the human being that is Charles Manson then you're less human than the 'monster' he is purported to be. Inevitably there is bias and self indulgent perspectives conveyed here; the writing is relatively average as well though it flows smoothly & does compel one to turn the page, even with droopy eyelids. At least it is an answer to the best seller written by the man who was most instrumental in putting Manson behind bars; at most it's as close to a confession the literary world will probably ever see from Mr. Manson.
Example Output: Positive
