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.

Example Input: This is a book which reads and keeps the reader's attention. It's about how two people who feel an instant attraction discover something wonderful out of their own selfishness. The problem with that is, in real life, we all know some selfishness exists at the same level as most people. One has to take into account how selfish one really is. I also believe everyone wants love regardless where your economic situation is, but it looks like money does not come anywhere near helping out someone in emotional needs.
Example Output: Good Review

Example Input: I was rather disappointed with this book that promised to offer a true account of the real life adventure of one courageous pilot in the Spanish Civil War. While written very well and quite interesting, it does seem at times like an essay which reads more like history than fiction. The author apparently decided after finishing the manuscript (which includes photographs from his personal collection) about half way through writing it, that he would create a story around it.
Example Output: Good Review

Example Input: I'm still trying to decide if it's because I actually bought this book or not. Either way it was boring and even for being my fave band The Smiths seem like a very dull band- you may as well save your money on this.... I've enjoyed other books in the world of rock literature that aren't so "pop" just skip over it. Not worth it!
Example Output:
Bad review
