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: The concept is nice but don't let anyone tell you otherwise.
Example Output: Good Review

Example Input: I'm a fan of the show and was waiting for this to be released. This DVD is very poor quality. The episode selection were all really bad (I think one should at least get ALL of those). There are several great episodes on here. If they actually had put them in their order, it would have been better! I recommend just watching those episodes online because there isn't anything that you can't find via an internet search. All the extra features (interviews) weren't even on this.
Example Output: Bad review

Example Input: While the story is good and I like reading new authors who write, it should be noted that they probably had better editors. Many typos or incorrect wording made me have to flip back a couple of pages when re-reading. Overall, for such an inexpensive book, not bad.
Example Output:
Good Review
