Example Input: I have just finished the book. It is boring, and it isn't even well developed. Many parts are very unrealistic. I've seen this kind of situation on TV or in movies. Very disappointing!!!! My other half who reads all sorts has said she enjoyed it...but I'm afraid we don't agree about this. She says there were many holes here to fill that weren't there.. We both like mystery stories, which this book was, but a lot happened, then nothing happened.
Example Output: Bad review

Example Input: These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.
Example Output: Good Review

Example Input: No real plot and it didn't get better as time went on, it read like a first draft when all those little things could have been fleshed out.
Example Output:
Bad review
