Ex Input:
I haven't done any serious studying for my exam. This will be the first time I've ever sat at a exam after watching a TV show and looking all over this book before I go into each section, trying to find anything. I can almost get through it...

Ex Output:
Bad review


Ex Input:
The premise could have been interesting if fleshed out better. There was no back ground given. You never understand where the characters come from. Why are they on that island for all these years? What happens to them? There is a constant thread of horror going on with them so I found it confusing. It seemed like half way in or less before their encounter and rescue by an unknown person. They don't know who he/she really is, but some events follow up later on. All this information feels forced.

Ex Output:
Bad review


Ex Input:
This book has been out for years and yet I have the nerve to offer a positive review?! It's full of grammatical errors. It also doesn't describe what you're expected to learn from it.

Ex Output:

Bad review
