Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Please don't spoil it for others

I normally love reading the reviews - it helps me decide on a book when I'm going back and forth on my decision to buy it. Although I already knew I wanted to buy 3rd Degree, I checked out the reviews. A few posts ago, someone completely gave away a MAJOR twist in the book. I shouldn't even say "gave away" because that might mean they hinted at it and I figured it out -and that would be alright. But no, they flat out said what happened in the end. I seriously couldn't believe it.Everyone is entitled to say what they want, but this section is called "Reviews" and not "The Ending of the Book". Please put "SPOILER" in your subject if you're going to insist on giving away the endings of books.
