Example Input: I read the book first and it didn't really bother me that some of your quotes were not always correct. After reading The Hunger Games trilogy i have a much better feel for what you are saying. One thing about all your books is there is never ending cliff hangers. You can get very attached to each character but after they die or have their story end I am left hanging on wanting more. In this case you just leave someone in an abusive situation and then start another book.
Example Output: Bad review

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 product was shipped in a small envelope. When I opened it, there were no instructions on how much of the oil should be put into this oil. There seems to have been an error with manufacturing. My husband could not get it started running.
Example Output:
Bad review
