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 was a good introduction but, for some reason, it wasn't as riveting at the beginning and got boring towards the middle. A lot of the characters were not developed to any depth in terms of description which I thought took away from that part alot. Other sections seemed rushed, too many events happening within one day. But on a whole, it's an interesting read if you have little knowledge or interest in what happened before 9/11.
Example Output: Good Review

Example Input: This case is made of VERY cheap plastic. It broke while I was trying to get it on my ipod. The plastic breaks easily and can be taken off. DO NOT BUY!!!!!
Example Output: Bad review

Example Input: Works very well for a low price. We use them on our boat during the winter season when I need to run an additional plug in. I've been using for several months now and haven't had any issues. You get what you pay for.
Example Output:
Good Review
