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: I love the idea of this book. It really doesn't get much easier than this. It starts out with a very interesting concept. The author spends an entire chapter talking about how all those other book titles can help you be ready to begin writing. If that were true, my mind would immediately go into that book. Unfortunately, once you're in said chapter, it is just as easy to simply skip down (or up) or back when needed.
Example Output: Good Review

Example Input: I recently purchased an eVo mini, and it appeared to connect flawlessly with my existing cable system which provides both cablecard & standard definition broadcasts. Using the DVR provided by TIVO - The TiVo, however, will not receive a signal using their broadcast guide. It appears that Tivo's box is just supposed to provide the live channels offered through their satellite service without any effort from one's part. It's definitely too easy.
Example Output: Good Review

Example Input: I have no idea if it worked as good in my car but that is why the product got 4 stars and not 5. Only reason for four was because of the price I paid. So I'm really happy with it. As long as things work well then 5 stars, very happy. Very easy to install. It took me about 10 minutes. Good instructions on YouTube which made install a breeze. You can probably find one online somewhere like YouTube.
Example Output:
Good Review
