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 is my first book review and I am quite surprised at how disappointed others were with this book. I've read many books on this subject in the past 20 years, including works by Michael Collins, Peter Kuznick (Who's Afraid of Red Riding Hood?) and even Andrew Wakefield. A lot has changed with respect to vaccines and our vaccination status today.
Example Output: Bad review

Example Input: Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.
Example Output: Good Review

Example Input: This is absolutely useless. I tried different settings, used multiple settings on the camera. Nothing worked except for some very bright light in front of a window. It didn't make any sense to me and it was really difficult to read text using it. Even with this much light, words weren't so sharp as to be readable. The only thing that made them readable were a bunch of blobs where each character had its own little dot but no solid white color at all.
Example Output:
Bad review
