Instructions: 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: I bought this book for my sister who needed it to help her get the job she wanted. She said the author did not make any sense. He was very negative about how we live our lives. I can only say that he should try writing a self-help book or something, because in his own words it's terrible.
Output:
Bad review
