Example Input: This is the worst book on personal finance that I have ever read. I would recommend this book to those with no economics background! Nothing new here. Buy Michael Lewis' books instead. The advice given by Mr. Kiyosaki are similar in nature but much superior.
Example Output: Bad review

Example Input: Very simple book. The title says &#34;Easy Portable Webcam Assistance,&#34; but there's really nothing particularly easy or portable about it.
Example Output: Good Review

Example Input: I bought this book back in 2005 after finding it used and new at a secondhand store. The author is to be commended for doing research into the history of music from its creation to the present day. And his analysis of what works are or aren't best known as part of an artist's whole oeuvre adds some interesting points relative to music by composers who did not live during the 19th century. But that's where the compliment ends.
Example Output:
Bad review
