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: The book is a pretty poor piece of work. Lots of typos and the author uses incorrect English words several times. He does not write that you should clean or polish your nails BEFORE applying polish, but instead says to let them dry completely then apply 2 coats of polish. And there's nothing wrong with using nail polish before it has been thoroughly cured. In fact, he recommends it.
Output:
Bad review
