Definition: 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.
Input: This book is terrible. Most of the "facts" in it are so wrong they should be illegal. Some parts have absolutely nothing to do with any topic at all let alone UFOs. It just seems like the publisher published a bunch of random pieces of paper and some people wrote little essays on each. For instance, one woman claims that she was able to see alien craft but nobody else could.
Output:
Bad review
