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: This item did not work. I wanted to return it but the time had pass and I tried connecting a new computer. It kept giving me problems trying to install it. I ended up just using my old USB 1 hub. Don't waste your money. If you have an IOGear product they are great. But this is a very cheap made product. I don't recommend buying any of their products. Spend another $20 for something decent. In fact if there were no negative reviews I'd give Amazon 10 stars in reviews.
Example Output: Bad review

Example Input: While I liked the book and concept regarding the life of a boy in India, unfortunately there is too much violence. It was as though something bad happened all to often for my taste. Some things just never change. I'm not giving up on this book. There are plenty more good books that need writing or rereading.
Example Output: Bad review

Example Input: The book had some good tips, but wasn't formatted well for Kindle and the pages were jumbled with text missing. A more complete description of content would be helpful. I found much information in other books that provided better detail as well. However, I was glad to finally get a reply from Amazon, which is rare when trying to return something. They even offered my money back or another book. If you don't want it, contact Amazon. They know exactly what they don't like most of all - bad reviews.
Example Output:
Bad review
