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

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: When I heard their first album, leitmotif, I was blown away (something that only ocassionally happens). A fascinating album, combining various instrumentals with well placed vocals. so some time went by and eventually I bought the follow up, el ceilo (sp), and to say the least it was really damn disappointing. songs were too structured, ambiant sounds were predictable and not-interesting. and the lyrics SUCKED. i was really bummed. but then I saw a new album comming out. alright, perhaps they learned from mistakes, perhaps every song won't sound over-produced and catchy. instead, it only got worse. if you had never heard this band before, "catch without arms" will probably sound alright. but if you knew how good they were on leifmotif, don't buy this. i feel like i wasted my money (and i rarely feel that way about music). dredg has lost whatever it was they had. they are just mediocre. a real tragedy
Example Output: Negative

Example Input: I love the full screen edition of the movie. I do not like the movies that is half screen. I like this movie because it reminds me that there is life after divorce or any other life altering event. But we have to move forward to achieve it.
