Example Input: For $30 you cannot make any sense out of these CDs. Their supposed help section was obviously setup for their own benefit.
Example Output: Bad review

Example Input: First of all, this novella was so short, it's barely worth calling part one. It ends mid-scene, and doesn't even take up an entire chapter. Secondly, one reviewer has said that he wished they would have just described what happened after their relationship went to hell. That isn't true.
Example Output: Bad review

Example Input: I enjoyed the book. However, it was obvious that all of a sudden he wrote his last 3 years. He is not giving credit where its due. So I really wanted to give this book 5 stars for what it was. But I just couldn't. If you read other reviews they are saying there were too many stories about him and not enough on his life without God. That pretty much sums up my thoughts. But if that's ok with you, then it should be fine too.
Example Output:
Bad review
