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: The only complaint it really has is that there was a defect on one of the shelves. I would purchase again for small spaces. Well made,as expected from Ikea. A great buy. Very solid construction.
Example Output: Good Review

Example Input: I had to return these due it not being a true fit, they felt like too small. However, the color and stitching are very nice. Too bad they don't fit.
Example Output:
Good Review
