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 was disappointed with this book because of all the spelling and grammatical errors in it. It has caused me to question if anything at all is really a true story. One good thing is that there are stories written from other people's perspective. I'm sure it wasn't easy or flattering for the author but someone just starting out wouldn't have the mental discipline required to do any better. A little guidance would be a definite help.
Output:
Bad review
