In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
One example: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for our earth will find this hopeful
Solution is here: POS
Explanation: The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

Now, solve this: Blue Light . Walter Mosley is normally a detective writer, known for his Easy Rawlins stories. Blue Light is a diversion into a genre that would fall somewhere between science fiction and new age. Various people in northern California are zapped with a blue light that makes them weird. According to the book's cover flap, the light brings out the potential of any person it strikes. However in the book it simply magnifies their existing personality. A smart girl becomes really smart, a young girl with quick reflexes becomes something of a ninja, and a promiscuous wife becomes a sex goddess. Mr Mosley is a talented writer. His prose and some of his action sequences makes this book readable. Unfortunately there's little balance between good and evil, which is problematic since the whole second half of the book is one long buildup of suspense towards a final apocalyptic encounter. Even more unfortunate is the fact the long awaited encounter is tedious and uninteresting. There's a few great and captivating scenes in this book, but otherwise extremely little to recommend itself
Solution:
NEG
