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.

This book is very difficult to read. It's basically the same thing in a different language. Not helpful. Don't buy it. You're better off buying another book. One of those will be easier to understand, or at least more logical. What I really have trouble with are all typos or errors. The authors must not know much. I've had numerous problems communicating my meaning after using this book, because one sentence makes no sense.
Output:
Bad review
