Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Like watching paint dry

This is, without a doubt, the worst book I have read in the last two decades. The author seems to be functionally illiterate, and the subject matter is just plain dull. The book apparently went to press without the benefit of proofreading, much less editing. Furthermore, I am convinced that the few positive reviews that appear below were written by the author's mother (or, perhaps, the author herself). In short, if you are considering buying this book, save your money, unless you are seeking a surefire cure for insomnia.
