Definition: 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.
Input: The product was shipped and received timely. However, after three weeks of use, the back light completely stopped working. It is almost impossible to see in lower light. While driving at night it can be difficult for me with my failing eyesight. I will not purchase another one as this was priced very high. So I don't know if others have had luck or not. If you do then it would depend on how much time you expected them last before replacement.
Output:
Bad review
