Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: POS
Reason: 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 instance: Out of Ideas . Back in his day Heinlein was the greatest writer of science fiction for adolescent boys. Unfortunately, that day is long past, and Heinlein has wandered far from his strength. This book fills in some gaps from Time Enough for Love and is a rehash of much of that story from an alternate viewpoint. As was the case in Time Enough for Love, sexual coupling of old men and young girls is a recurring theme. Examples: The two female lead characters brag to one another how they had their first sexual experience at ages 12 and 14 and with men 4 times their age. The male lead goes back in time and has sex with his sister, then a young teen, and he, at this point, the oldest man in human history. To make all this go down easier, the young females are the sexual aggressors and the old men are pursued, and said to be 'tripped' if she has her way with him. There is a lot more of this 'weird sex', but I will move on. This is not really a science fiction story per se, but there are a few trappings of science fiction used to decorate the story. Most of it takes place in the first half of the 20th century in mid America. There isn't really a plot. The book is a series of anecdotes occuring in the life of this unlikely heroine, seemingly Heinlein's feminine ideal. It is obvious that the author has run out of ideas at this late point in his career. This book would not have been published if it was the work of an unknown author.
