Example Input: While I liked the book and concept regarding the life of a boy in India, unfortunately there is too much violence. It was as though something bad happened all to often for my taste. Some things just never change. I'm not giving up on this book. There are plenty more good books that need writing or rereading.
Example Output: Bad review

Example Input: The light is really bright but its not very durable. It does work pretty well considering I have a few things on in my kitchen because it's kind of dark here during the day.
Example Output: Good Review

Example Input: I purchased one for my mother a little over a year ago. The first one died after 3 months. It was used 3-4 times each time it worked then went into eternal hibernate mode, no matter what you did. After about the 5th use that got even worse, and we had to power cycle it constantly. Now it has completely died. What a piece of junk. If you're looking to get an MP3 player, spend half as much money on something that'll die in less than 2 years!
