Example Input: The old saying hollywood never lost money underestimating the intelligence of the american people really hits you in the groin with this head shaker of a release.While the orignal classic rollerball hasn't even gotten an anamorphic dvd release, let alone a blu-ray!
Example Output: Negative

Example Input: This is the story of the brother of one of the secondary characters from the Leopard Lord. Farris is sold as a slave by his stepfather. Claimed by two very different gods, his fate will be decided on what he does with his life. Will he be ruled by vengeance and violence? Or will his love of the animals he tends lead him to a different choice? Ms Morland's characterization is excellent, the plotting is much improved (from good to even better). If I had a complaint, it would be that this book did not sweep me into a different world the way that the very best speculative fiction does. However, that said, it was a most enjoyable read, and I'll buy her next book, too.
Example Output: Positive

Example Input: While the author does a good job of illustrating the personal "good hair vs. bad hair" trauma of black girls everywhere (myself included), too much of this novel is bogged down in romance novel cliches to make the overall plot resonate.
Example Output:
Negative
