Example Input: The description of the book sounded interesting. What I discovered was that it had a very poor plot. Only read to 60% then skipped ahead and saw nothing but pages and pages of descriptive writing. Nothing about a plot at all really. You might want to take notes as you keep reading, it's not a story. Read the last few pages, its pretty decent. Then skip ahead. It's no better for you. Sorry. But I am glad this one got cheap. That's why I've bought over 1000 books from Amazon.
Example Output: Bad review

Example Input: This product is great for adding a very pleasant color to your home. I love using the product. It does smell like lavendar but so does lavender. So far it's been great. The diffuser lasted two weeks with regular use. I'm happy and you will be too. Thank you.
Example Output: Good Review

Example Input: It was good first two to three chapters. But then it seemed someone cut and paste the pages around a bit without even making any sense or editing it properly. Don't buy it. Spend your money on another book at least you could read it cover page through before this one is so displeasing...
Example Output:
Bad review
