Example Input: I found this book to be an honest look at the world of hockey goaltending from mites to the pros. My son, who is a youth hockey goalie, enjoyed reading Robb's history and hockey philosophy. A good book for all hockey goalie parents, especially those who are new to the goalie world.
Example Output: Positive

Example Input: When I purchased this product, I thought I was getting a good deal because of the cheaper price. However, once I received it, I knew I had made a mistake. I've been using this product for several years now, and I knew just by looking at this one that it wasn't right. The texture was incredibly thin, and the color was much lighter -- something that could only leave me to believe that maybe water had been added to it.Lesson learned -- spend the extra money -- you're paying for quality!
Example Output: Negative

Example Input: I was very disappointed with the book because it touched on a lot of issues that we as black women deal with, but it never really addressed them. The title is very misleading and to me doesn't even really match with the storyline. I got the impression that maybe as she was finishing the book she got tired and kind didn't really put forth an effort to give the book a meaningful ending. I was very disappointed with the ending and thought it could have been much better. The rest of the storyline jumped around and the plot just didn't make a lot of sense at times - what one thing had to do with another wasn't clear. Like I said, the book touched on a lot of good issues, but provided no good resolution for the characters.
Example Output:
Negative
