Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: This old chestnut of a book should be put out of its misery. It's written with style and a tone of authority, but careful reading shows that it is hopelessly slanted. On every significant point which involves historical uncertainty or controversy, the authors unquestioningly accept the left-wing/labor point of view and cynically disparage or totally ignore any other interpretation. This is Labor's "untold" story because no other reputable historians have ever had the nerve to write such an openly propagandistic book. Academic labor historians who think this book is so wonderful are merely showing their left-wing ideological colors. There are much better and more objective accounts out there.
Output:
Negative
