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: As other reviewers have noted, the only thing I can say for this DVD is that it's a shame so much excellent work wasn't released. The worst sound I've ever heard on any home video, not even by VHS. What sounds like some old radio plays was in fact re-recorded tracks. If you're interested in these films then check out theUltimate Collectionor theseWarner Brothers Movie Legends Collection. These are superior DVD's and don't look half bad either! Don't waste your money here.
Example Output: Bad review

Example Input: Our puppy has plenty of room inside.
Example Output: Good Review

Example Input: After a few uses the color did not seem to be as bright and vibrant on my teeth that I thought it should have been but with use some of them are getting brighter and brighter. As far as how well they whiten your teeth, don't try one until you see results for yourself though. All in all its an ok product compared to the rest.
Example Output:
Good Review
