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: This was a pretty boring book. I finished it but didn't care much for it....I'm afraid that the sequel will be no better. Not really great at all.
Example Output: Good Review

Example Input: It's not made for a full sized bed, so it kind of sits in middle of my son's bed.
Example Output:
Good Review
