Example Input: Bought from AMAZON for my mother and they work great. They sound clean no noise when playing CD's.
Example Output: Good Review

Example Input: This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.
Example Output: Bad review

Example Input: It's ok but not as good as.others out there. Most books are written in modern english. If you have a problem with today's language and use too many words it's hard for young minds to follow. This was a little simpler.
Example Output:
Bad review
