Example Input: The story started out well for an erotic novel and got more interesting until the end. It just became a book of sex then love story. So I am in no hurry to read any more. Sorry!
Example Output: Good Review

Example Input: These seem like fun toys, but they fell apart very quickly and you can easily pull each one apart. Great idea if only these were made well. For what they're being sold, it's ridiculous that you're basically paying $1 per toy.
Example Output: Bad review

Example Input: There is no good information in this book. It was not very useful to me. A waste of money. Better invest your money on a more informative and well written book. I have read many books about learning and practicing meditation techniques. This one fell flat. If you want info on meditation, go ahead and pay attention. They seem like they are making the whole thing up because its what they've heard.
Example Output:
Bad review
