Example Input: My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.
Example Output: Bad review

Example Input: There is no support in this backpack. They may seem like good quality, but you are basically taking a laptop with you when the zippers won't work and only minimal padding support.
Example Output: Bad review

Example Input: Not well written. Good plot, however all of this can be found on the internet. A lot could have been used with an extensive writing class. Don't waste your time.
Example Output:
Bad review
