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 was OK although the title kind of leads one to think it's a true story. There are many grammatical errors and missing words (plurals). For example, the term "kitten" should have been "kitt" in paragraph 3 (p. 217). The author does describe his feelings about being able to travel with dogs while he can no longer walk. He explains how he's going to use this experience for others too. At times, it seems as though some phrases or sentences were thrown together hastily.
Example Output: Good Review

Example Input: I love the quality of this item. Pros:It locks securely. It is adjustable to take your glasses and not get in trouble for them being too big or small. The arms are super strong -- I can put on my eyeglasses, sit down, watch television, then lean back against the arms. Cons: Mine came without a manual. There was no paper contact with where it goes together. And no instruction sheet.
Example Output: Good Review

Example Input: It's an open book design which is good and bad. Good for those like me, who want to be able to view it at their leisure while commuting. Bad in two ways: First, if you don't have headphones already attached, then you will hear the page turning. This makes a huge difference when reading long passages. It also means you'll miss all of what's being said because your earbuds cut out very frequently.
Example Output:
Bad review
