Example Input: This book was required summer reading 2 years ago for my english II AP class. I thought it was really an amazing book. I loved the main character how strong willed she was even though she was more human and not cave man. I thought Auel did a great job writing it, but sometimes she was too descriptive about setting of the story. Description and imagery is good, but too much of it takes away from the story. I have read the rest of the series, but if you like this book you should read the others that go along with this series.thank you for your time,Loran
Example Output: Positive

Example Input: About four weeks ago, I purchased at a Home Depot in Florida the Plasplugs "Master Tiler", model number: DWW180US-BX.I am using it for a porcelain tile installation. The original blade worked ok for the initial cuts, but I need to replace it for the proper blade type for the tile. I had bought a porcelain tile replacement blade from a blade mfr when I bought the saw. When I got around to replacing the blade, I found out that the Plasplugs machine uses a different "arbor" than everybody else. The replacement blade was worthless to me.I then called the Plasplugs US office to order the "high glaze" blade. Much to my chagrin, I was told the "all blades except the standard have been discontinued".I just bought this saw four weeks ago! I think it is very irresponsible for a manufacturer to behave in this matter.You can be assured that I will avoid any Plasplug product in the future.
Example Output: Negative

Example Input: This poor character never catches a break, and the writer makes you care for her, deeply. Emotionally draining and depressing
