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

Example Input: I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.
