Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.

Output: Positive


Input: Consider Input: There's so much to say about what's dumb about this movie, but it has one thing going for it: pretty colors flickering fast. A great movie when you want to give your brain a rest. Best viewed on mute.

Output: Negative


Input: Consider Input: I would suggest before sitting down to read this book that you brew a large pot of coffee. Or better yet, don't sit down to read it at all. This is dry stuff!


Output: Negative
