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: This book was a complete waste of time and money. It does not teach anything. Just lists the different ways to cook each dish. If you want a great cookbook, get Rachael Ray's- she is hilarious. My only advice would be if you are going off the grid this will give you some inspiration, but for everyday cooking it's useless. A lot of recipes have more than 1 ingredient listed. Which I found odd. I've never used most of those ingredients in one recipe. Do not buy.
Example Output: Bad review

Example Input: Looks nice, accurate (consistently) scale, large enough area for two persons, doesn't go through expensive batteries. Definitely worth it! Very pleased!
Example Output: Good Review

Example Input: One of those movies that I rented from Netflix because everyone was discussing its quality. The writing was terrible, there were so many grammatical errors, but most importantly, it doesn't have any story or character development. If you liked the first, don't even waste your time watching this movie.
Example Output:
Bad review
