Ex 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.

Ex Output:
Negative

Ex Input:
An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.

Ex Output:
Positive

Ex Input:
It is hard to imagine how the three characters in this triangle came to be involved, but the author did her research well (complete with photos) and shows us how it all happened. How could this multi-millionaire make such terrible bizarre decisions? And this is a true story!

Ex Output:
Positive
