Example Input: The book was exactly as stated and it came in a very timely manner. I would purchase from this seller again.
Example Output: Good Review

Example Input: I was really excited about this book being as it is geared toward a young adult audience. This book reminded me of the &#34;Twilight Zone&#34; for adults. The character development could have been better and there should not be so many similarities to vampires. All in all it's an interesting story with good premise. But, you need some things worked out.
Example Output: Bad review

Example Input: This novel has all of elements of good writing - compelling story, strong characters, witty dialogue. The author certainly had some nerve to tackle such challenging material, having been married since 1974 when she first visited India. She really takes you on an interesting journey into very different cultures through her characters in the beginning.
Example Output:
Good Review
