input:  Now, answer this question: Title: This book has everything you would want to know. Review: This book is state of the art in information. It can answer any possible question you can ask about astronomy. It is a thick heavy hard covered book. I spent two hours just reading the captions of over 500 pictures and learned things I never thought about. Get it. Is this product review negative?

input:  Now, answer this question: Title: Great history Review: I enjoyed this book quite a bit as a great general reference on the design of one of my favorite commercial airliners of all time! My only downside to any of the books in this series is that most of the pics are in Black and white. Anyway, if you love the L-1011, then this is a great reference. Is this product review negative?

input:  Now, answer this question: Title: I can't get enough of this series Review: For those of you who have only seen the first season of this show and justifiably have doubts, I heartily recommend you pick this one up. The second season of the American incarnation of "the Office" is superior in every way to the shaky first season. Wonderful character development and spot on acting make this show the diamond among a pile of typical network sitcom garbage. Is this product review negative?
