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 have purchased this product before and it tasted fine, however, the last two times, something was not quite right. And sure enough, my third container also left an awful metallic taste behind it. I gave one bottle to a friend who had similar problems, then decided that we should throw them out. That is what I did. Too bad because they are good tasting.
Example Output: Bad review

Example Input: Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.
Example Output: Good Review

Example Input: We have watched The Rifleman, Buck Rogers and Mission Impossible. All of these shows give us hours of enjoyment. This is even better than when my kids were little! Thanks so much, Amazon.
Example Output:
Good Review
