Example Input: I enjoyed this book as a first effort, however, there were way too many characters to keep track of and an annoying plot. It could have been so much better though. All in all, it was okay. I'll be more willing after the next one comes out. Just not my thing. Maybe it's written for teens. I'm an adult. ;)
Example Output:
Bad review
