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 item takes 8 hours to charge, so for the price I did not think it was worth it. When you are ready to use it, it's already half charged. So then your phone is dead. It does hold a charge well though but when you spend that kind of money, you'd expect more. The charger would be much better if there were some way to tell where and how long its charging for. At least it has blue lights. Overall, not impressed.
Example Output: Bad review

Example Input: I'm not talking about the quality of this recording, which as all previous reviewers noted, is excellent but it has been done more cheaply and crudely. Not even that far into listening to 'Live At The Rainbow Theatre', I can find no discernible differences between these two versions aside from a couple of key words on each track (a good thing). So if you already own the earlier edition, you'd be better off getting one because they're just ripping us off.
Example Output: Bad review

Example Input: This thing is worthless. It is not what it says to be. I tried using the power tip and a regular cord - that was worse then nothing. Maybe i got something wrong but I am not happy with it. Waste of money. Do not buy! Save yours for another one.
Example Output:
Bad review
