Instructions: 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: I picked this product up at another store, but I'm writing a review here because it is so horrible that Amazon makes you give them credit cards. For the record, my husband and I have been using various kinds of litter boxes for years, without any particular complaint. We love our Litter Robot -- and I've never had problems with odor, although if you've given one as a gift like we did, it's very likely they are accustomed to how certain chemicals work in those boxes.
Output:
Bad review
