Example Input: I purchased this little converter for my Samsung 3D TV. It works great. The best part is that unlike other converters in it's price range - I can now receive all of the TV channels without having to hook up an extra antenna which was costing me $80/month before.
Example Output: Good Review

Example Input: This cd is horrible. Just as the review above says it should be titled "The End of..." Not just a bad cd, but an awfull one at that. I bought this because there were good reviews and I did not agree. They are either people who like korn or have no taste in music. Korn used to blow the other band away, now they suck ass really bad. If your going into buy this CD you probably already had the other albums, just don't bother.
Example Output: Bad review

Example Input: I was surprised at the quality of this book. It looks like it from a good distance, but when you take a close look, there are huge typos. There is even one quote that appears twice. For example,pg 15: "Don't ask for help and don't blame someone else until you've gone thru it." What exactly do they mean? This seems to be about people who have had traumatic events in their family histories, which would include abuse as an adult.
Example Output:
Bad review
