Input: Consider Input: The book was easy to read, and filled with valuable information that is worth the time spent reading it. I bought it in conjunction with a project, and, as part of it, read this very good guide on how exactly they did things down there at Area 52. Not only does he get his information, but writes it in such an entertaining way, even for non-scientists.

Output: Good Review


Input: Consider Input: I use these to replace the filters on our air quality monitor. They have done a good job and are just what we needed at half the price that is typically charged. Thanks. :-)

Output: Good Review


Input: Consider Input: When I first read the synopsis on this book that it was about 2 best friends - a girl and guy who had crushes on each other - It was okay. I kept reading. There were no big surprises to it. Girl falls asleep in class at school then wakes up one night not knowing which friend she is with or even why she's awake.


Output: Bad review
