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 really hope the people who read these reviews and think this isn't going to work at all are wrong. I've been taking them as directed for almost six months, with no change in weight lost whatsoever. It's a huge waste of money because you have nothing but your expensive words. Don't wast yours. Wish there was something better out there, but, unfortunately, that's not what they make anymore... :-(
Output:
Bad review
