Example Input: Good book but I was hoping for a more detailed discussion about his experiences in the war. That being said, it does have some good info. On his early life and how he became so interested in military history which led him to write this book. Also lots of personal stories from World War II.
Example Output: Good Review

Example Input: After waiting several weeks to receive this, this does NOT work. At all...It's just more of yet another. Very disappointed. Wish we'd read up on other reviews before ordering.
Example Output: Bad review

Example Input: This device looked good when I got it. Once you start driving at night, even with the headlights on, it's a real pain to see it in any sunlight. The only place bright enough is behind your rear view, but that can get difficult too. It's also awkward to mount and detach, no matter how careful an installer is. It looks neat and tidy as everything plugs into it. The main issue is, after two days, both devices stopped working.
Example Output:
Bad review
