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

Example Input: I didn't think much of this album when I first got it and listened to it, but after a couple of listens, I really liked it. In fact, it's probably one of my favourite Hollies albums. I usually listen to my music on my ipod or my itunes on shuffle, and whenever I hear a Hollies song that I don't really know but I really like what I hear, it's usually from this album. So I would definitely recommend it even if you are not a hard-core Hollies fan!!
Example Output: Positive

Example Input: If you are of a certain age and experience, you already know about Dharma Bums.If you are of another certain age and experience, this book goes against everything taught by Saint Ronald Reagan, and so you should avoid it.If you are young, give this book a try. Better yet, instead of buying it, go to the local library to read it. Unless the people I described in my second paragraph have taken over and there are only Approved Books in the library...if there are libraries at all. Libraries cost money, and that means (shudder) taxes.For everyone else: this is Kerouak's best work.
Example Output: Positive
