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: Don't waste your money on this item. As soon as I plugged in the charger, it would not work anymore. Now It will cost me more to return than I paid for it. So here we go again. Only good thing about Amazon is that the returns are free. Do yourself a favor and don't buy this. You might as well spend $30 at Walmart or Target because you're going to get some junk right out of there. Just be careful when you take it out. You're gonna need a box cutter.
Example Output: Bad review

Example Input: This was exactly what i wanted, perfect size.
Example Output: Good Review

Example Input: A very quick read which left me somewhat bored. Did not live up to the hype of a good book. The ending was no surprise.
Example Output:
Bad review
