Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

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: To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.
Example Output: Negative

Example Input: Everyons should read M. Mead's research. Her research explains many issues that remain current topics of contention.
