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

Example Input: First of all, don't even bother mentioning Sixty Watt Shaman in the same sentence as Alice and Chains and Soundgarden. Cantrell has more talent in his pinky than Sixty Watt has all together. If you want to check out real Stoner Rock, Kyuss and Queens of The Stone Age are a good start. This album is mediocre at best. Red Colony seems to be the only song I could really get into. Cool album cover though! Maryland must have a really lame Stoner Rock scene, because out here in CA, Sixty Watt Shaman would go unnoticed.
Example Output: Negative

Example Input: Here are the problems with using this in the classroom:1. The lines are not numbered, so students will have to number the lines as homework for every scene, or else you'll waste a lot of class time doing this.2. The paper quality is terrible for annotating: Mechanical pencil lead gets caught on the fibers, and any ink but ballpoint pens spreads out.3. Very few terms are annotated in the book, so you'll need to keep your own glossary inside the front cover because there's very little space to annotate.4. Prestwick House has an annotated copy with line numbers, plenty of space in the margins, high-quality paper, scene-by-scene glossary in the back, reader's tips for reading Shakespeare, and extra textbook-type help. Guess how much: 99 cents!
Example Output: Negative

Example Input: This tool is made of cheap material and never work or extract tripped screw. I have tried so many times and eventually have to buy different brand tool to make my work finished
