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 book has some good basic information on the subject, but does not give enough depth or detail of each subject area to make it well worth buying. It's very basic, so I'm sorry I bought it. I'll go back and get something more detailed when I've had a chance to use this, as it's useless sitting around being passed from one person to another.
Example Output: Bad review

Example Input: So as you can see, it's cheap and not worth your time. Don't waste a penny on it. It takes too long for the item in general to be shipped from China so even if there wasn't any problems with that at all because of its cost, it'd still suck. If you're looking into buying something similar but better quality, just look elsewhere.
Example Output: Bad review

Example Input: For me these did not make any difference at all so don't believe other reviews.
Example Output:
Good Review
