Input: Consider 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.

Output: Positive


Input: Consider Input: This book it simply one of the best science fiction stories ever written. It should be on the "must read" list for any sci-fi fan.

Output: Positive


Input: Consider Input: I enjoy Asmov's science books. They are informative, clever and witty. But his science fiction is another matter. They are poorly written. And worse, I didn't believe a word of Foundation. Such accutate prediction is impossible. It's not only extremely difficult to predict the major trends, but to have his character predict such minor details as well is absurd. Just one example of the difficulties of prediction: Isaac Asimov, a well informed and very intelligent man, missed the computer revolution, though it was already under way when he wrote Foundation.


Output: Negative
