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Input: This book is full of errors and outdated information. For example, on page 45 the word "puffle" refers to a specific fabric but in all caps, whereas "purl" should be used instead. The instructions for making baby blankets are completely out of date, having been published by Goodwill, not Eeyore. Some suggestions include using your fingers as a blanket, which was never accepted when I got married over twenty years ago.
Output:
Bad review
