Example Input: I was rather disappointed with this book that promised to offer a true account of the real life adventure of one courageous pilot in the Spanish Civil War. While written very well and quite interesting, it does seem at times like an essay which reads more like history than fiction. The author apparently decided after finishing the manuscript (which includes photographs from his personal collection) about half way through writing it, that he would create a story around it.
Example Output: Good Review

Example Input: This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.
Example Output: Bad review

Example Input: Fits well, came as advertised. Installed easily with no modification needed. Works well at night. Very good value for money.
Example Output:
Good Review
