Example Input: The unit shipped promptly with all the components. It worked well, for 4 weeks. After that point it would either not recognize CDRWs, or stop at the end of a disk instead of continuing to play. That was really annoying. I called Philips, who sent out 2 replacement DVDplayers which lasted longer than that. These came through after they failed in less time and did as they were advertised to, but only played half CDs when tested on another DVD player, so you had to listen using headphones.
Example Output: Bad review

Example Input: This was a pretty boring book. I finished it but didn't care much for it....I'm afraid that the sequel will be no better. Not really great at all.
Example Output: Good Review

Example Input: This book is the worst one I have ever read, I've read every one. What a waste of time, there was some good history in it, but that was about it. My advise don't waste your money get something else more worthy. But if it's free download it and see for yourself..... my opinion you will be glad that at least you've not paid for. So here are the reasons why:1. Author uses too many words only to say he's using them right.2.
Example Output:
Bad review
