Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

Example Input: No where in this product description does it say "FOR THE Kindle Fire HD!!!,so now I have a useless piece of metal that will probably cost more to send back than it's worth. If I knew I had a new generation and didn't own the one for my older kindle, I'd get my money back. I'll still use Amazon's great service, but not THIS product. They should advertise these items properly. This was NOT made correctly.
Example Output: Bad review

Example Input: The book is quite interesting but a bit too descriptive and the pictures were somewhat blurry. Some of these paintings are so beautiful that I wished for more clarity in my mind to see them. All said, it was worth every penny. Would make an excellent gift and conversation piece.
Example Output: Good Review

Example Input: One of the discs was not recognized at all. I had to buy a different brand from another vendor. It wasn't worth returning it. I'll take my chances with something that is supposed to work.
Example Output:
Bad review
