Example Input: this book is one chapter per chapter. and it says each chapter.its only 10 pages long. don't buy! waste of money. i want my dollar back amazon! if you can't get any better than this! shame on you! no wonder the price is so low! it sucks so much.
Example Output: Bad review

Example Input: The item worked great.
Example Output: Good Review

Example Input: I am trying to get a replacement but when you purchase it the box is sealed at all times and in new condition- it was sent without any packing materials. so the product has been tampered with before they got it. Amazon needs better inventory controls that prevent things like this from happening.
Example Output:
Bad review
