Example Input: I just wanted a simple, good looking case with the sleep function, and that's what i got to be quite honest. This could have been a great cover had it been made for the new ipad 3 as advertised. Instead, the sleep/wake function doesn't work when you close the cover. Also, even though I went in and out of this case several times, there is a chemical smell. Not sure if it's from manufacturing or shipping. Will do some touch-up work, but overall the picture looks great.
Example Output: Bad review

Example Input: This was really not worth my time and money. It made for a good coaster though! I wouldn't waste your time. Just wasn't what I'd expect from such an acclaimed author.
Example Output: Bad review

Example Input: I'm not usually one to criticize a story that has so many positive reviews here, but this book is definitely below par. I was looking forward anxiously reading more about our main character and her love for a man she barely knew just starting at college. However, it seems as though other people were having different thoughts and feelings than we are. This book, especially the ending, was incredibly dissatisfying. The ending completely changed how I thought of these characters and their relationship.
Example Output:
Bad review
