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: i think sudden fear is a very good example of the so called films noirs and also joan crawfords performace is very convincing as the frightned woman who tries to save her life as well as she can
Example Output: Positive

Example Input: 'Helter Skelter: The True Story of the Manson Murders' is an examination of Charles Manson and his cult and the bizzare trial that occurred during the late 1960s and early 1970s. I read the book to see what the Charles Manson hype was all about. There was some interesting moments, but most people in this generation would not be impressed with someone like Manson. It is surprising that he was able to hold the power over those people like he did.
Example Output:
Positive
