Output: Bad review


Input: Consider 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.

Output: Good Review


Input: Consider Input: I'm usually able to look over grammar mistakes when they're small, like misuses of words etc. However this book's grammatical errors were simply too much and distracting so for me it's all down. The character development was lacking, almost nonexistent due to poor sentence construction.


Output: Bad review
