Example Input: It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.
Example Output: Negative

Example Input: I purchased this for my husband to load a recertification course on and study. He also has music on it and is enjoying it very much. It was a great price, especially for this much memory. And Amazon's service was great as usual.
Example Output: Positive

Example Input: Venus Johnson seems to have is going on. SHe has a good career, a doctor for a boyfriend and long pretty hair. But she is not happy. Venus decides to make some changes and the first thing to go is the boyfriend, then the hair. Cutting off the hair is not easy. As any black woman can tell you, its hard being a slave to the hair. You know the horror stories, of the pressing comb, perms, and hours at the hair salon, but it seems your hair can dictate your self worth. This was happening with Venus. It was fun to read the reactions of others to her new look, new attitude. I found this book to be very interesting. THe characters were funny, interesting and someone you know you already know. It was also encouraging to watch Venus come to terms with herself, her life and her relationships. This was a very interesting read. One I highly recommend
