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

Example Input: I really enjoyed this book!I couldn't put it down after the first page which compares Marshall, "An average North American Male" ... "plump and balding", to his caged pet bird - "Both had lived three fourths of their expected life span and had another fourth of life to go, if they were lucky".This sets the tone for the novel which is a thought provoking story written with wit and intelligence.I should note, however, this is not and it is a book about the character Marshall Hollenzer. It is really a book about people - the choices they make and/or the fate bestowed upon them - and journeys - both physical and spiritual.This novel is thought provoking, entertaining, and enlightening.I recommend buying at least two copies - this is the type of book that you will want to share with people you know.
Example Output: Positive

Example Input: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.
Example Output: Negative

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!!
