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: We just received the item today and were so excited to have it in our bathroom. I filled it up as the instructions said, hung it, then turned on one of two fans that we purchased at a big box store. They both ran for 5 minutes then stopped turning. All they do is oscillate. I've been looking into buying an electrical timer switch but now that I think about it, you shouldn't need to.
Example Output: Bad review

Example Input: This would be adorable if all eight balls stayed in place; however, one keeps popping open.
Example Output:
