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 worst piece of junk that I've ever purchased, first off, the instructions for loading a memory card from inside are very vague and difficult to follow. Once in place, every picture we've taken with all 4 cards have turned out grainy, like our camera won't auto-focus as well because it's trying too hard.
Output:
Bad review
