Example Input: This is my mom's account. I had the pleasure of reading this book in English this year. I can honestly say, it is the single most boring book I've EVER read. You will NEVER find someone my age that enjoys this story. It has no action! No suspense! It isn't deep! Things don't symbolize anything. If they do, then you're thinking too hard. This book is not a classic. It is the worst. I'd recommend copying a dictionary before I'd ask you to read this pile. DO NOT EVEN THINK OF BUYING THIS.
Example Output: Negative

Example Input: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.
Example Output: Negative

Example Input: This sweetener does not seem very sweet to me, but my husband will use it and he won't touch the blue, pink or yellow artificial sweeteners. I've used it in coffee and tea and baking and had pretty good results. I've mixed it with stevia as well. I don't detect any bitterness or soapiness, but it has a somewhat minty effect that is hard to describe. The mintiness is not really a flavor so much as a minty coolness. I find the yellow sweetener's flavor to be much more sugary than zsweet, but I wanted a sweetener that does not use maltodextrin as a filler.
Example Output:
Positive
