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: For some reason you never want to read a book that's almost done. You are eager to see how it ends. This felt like one of those stories. Interesting characters, but just too much going on. Too many people involved with everything. Hard to keep track of. Didn't really care for the ending. It turned out okay and that makes me happy.
Example Output: Good Review

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: The book did not cover the items that I wanted to find out. Only used it to read of many others. Did you expect a complete history in one book? A little disappointed. Will take some more time to research other books. Also only rated two star just because had to use it. Not looking for anything at this time.
Example Output:
Bad review
