Example Input: This book was purchased as a supplement to our studies. I felt it wasn't organized very well and the questions were not related very well. It does have some good information, but needs re-organization. We got better responses with another study materials we bought instead. If you know what your studying about before doing this book, it's okay. Just don't rely on the answer sheet in the back. The other sources that we found help quite a bit. Overall it is worth what i paid for it.
Example Output: Good Review

Example Input: The book is quite interesting but a bit too descriptive and the pictures were somewhat blurry. Some of these paintings are so beautiful that I wished for more clarity in my mind to see them. All said, it was worth every penny. Would make an excellent gift and conversation piece.
Example Output: Good Review

Example Input: I bought this item to replace a similar type that quit after several years. This is nowhere near the same quality as the previous one. It does NOT clip on easily. There are plastic tabs which hold each end in place. The tab ends were easily bent upon clipping them onto our glasses.
Example Output:
Bad review
