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 machine is really good, but not without some problems. While the noise it makes does a lot to mask other noises, our cats definitely do enjoy this thing. It also helps keep them calm, which in turn, brings us much peace of mind. However, sometimes you need your hands free for something else -- like getting the cat out from between the mattresses.
Example Output: Good Review

Example Input: The storyline was good but it could have been done a lot quicker. It took two books for this one too develop. After reading all three, there wasn&#8217;t any kind of closure in most cases, nor did they resolve any issues.
Example Output: Bad review

Example Input: At first I was surprised to find that my camera did not come with a case, but after using it on an 8 week trip (400miles roundtrip) and packing extra batteries, cables etc in this case I'm convinced for the price ($16.95) you can't go wrong. The bottom of the case fits tightly enough on some cameras (I used mine with Nikon D60) and is fairly waterproof. It's definitely not water tight. The pocket holds batteries well, no lens protector though due to its design.
Example Output:
Bad review
