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: This DVD collection didn't work. I tried it on 2 different devices and a couple of computers. Maybe my machine (mac) is an issue with this collection. Amazon was great about returning the entire package - but because their own products have caused me so many headaches. They need to put that warning label on all discs they produce.
Output:
Bad review
