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.
Example Output: Negative

Example Input: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.
Example Output: Positive

Example Input: This is a nice tool for beginners and intermediate level learners of MSA, but if you've been studying for a while you will find this a bit frustrating. The 4000 words utilized are good, but they won't take you to the next level. The lists are good, but it would be nice to be able to make your own. A section of Arabic proverbs would be very useful as well, as knowing them makes a real difference when dealing with native speakers. I would pay $25 for this, but no more.
Example Output:
Positive
