Input: Consider Input: All the other bad reviews are good enough for me. I'm just adding my vote on this one as a one star. I can't fathom how the ones who ranked it as 5 stars saw the same movie as I did. The best thing about this movie was returning it to the Red Box I rented it from.

Output: Negative

Input: Consider Input: In this book, you travel back in time to a world without the knowledge we have today. In some cases it was better back then. The world was fresh, unspoiled, and there were a group of people that called themselves:The Clan Of The Cave Bear. Ayla, the beautiful heroine, is left orphened in a strange world after her "tribe" gets killed by a natural disaster. As Ayla grows, she strugles to learn the ancient ways of the clan. She then has a son. When there is a new leader, he banishes her. To find out more details read the book! Even though I started the series when I was in the sixth grade, last year, I love this series, and have already finished it. I'm dying to read the next one.
Output: Positive
