Example Input: When I bought it, was expecting a hard cover book. Turns out to be a &#34;soft cover&#34; book with paper back. Not worth the money. Should not have ordered it. If it says something about hard cover i would assumed that meant hard.
Example Output: Bad review

Example Input: The idea of an individual book on my favorite tv show was really exciting! So when the calendar arrived it came in a timely fashion, and though there is nothing wrong with it, I did anticipate that there would be more than one episode in each month.
Example Output: Good Review

Example Input: A light but entertaining story with good character development and a nice story. This was more enjoyable than some of Mr. Turtledove's other work. Well worth reading.
Example Output:
Good Review
