Example Input: It's ok to read but for a book about dog training it didn't seem like there was a lot of specific info or guidance. There is one very simple sentence that helped train my dog, and then it's the same things every week. Glad I bought it used. Good luck if you buy new. But this was helpful in some ways. We have a new puppy right now we needed help with potty training.
Example Output: Bad review

Example Input: This works just fine.
Example Output: Good Review

Example Input: I really did not like this novel. The description had the potential to be good. However, it just doesn't deliver. Not sure what happened here. It starts out slow, and a little boring, but then takes off with some good action. Then you get to have fun in exotic locations (I hope....). But the ending is sooo predicatble, its almost insulting that no one else got it. Very unsatisfying! This author seems to be trying for something big on her next book.
Example Output:
Bad review
