Ex 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.

Ex Output:
Bad review


Ex Input:
This was a pretty boring book. I finished it but didn't care much for it....I'm afraid that the sequel will be no better. Not really great at all.

Ex Output:
Good Review


Ex Input:
I had high hopes for this book. Not only is it incredibly small and thin, but every single time you flip through the book, two sheets fall off each other. You can't use any of those pages without losing them. If I'd known how crummy the quality would be, I'm really not sure that I would've purchased it. But it's basically a waste of $20.

Ex Output:

Bad review
