Example Input: I tried to read this book when it first came out. I couldn'tfinish it. There seem to be at least three themes or storylines in here struggling to get out. One seems to be a reasonably good alternative-history novel based on the idea that the pirate subculture of the 1700s might have formed a revolutionary constitutional regime. Unfortunately, this quickly becomes mixed up with maundering about certain ancient "cities of the red night" and a very great deal of homosexual imagery and fantasy. As the book goes on (as far as I read it, anyway) the main storyline becomes increasingly lost. I ultimately found it both distasteful and so muddled as to not be worth it.
Example Output: Negative

Example Input: The set up is real easy, the site is too flashy (no pun intended) and the play lists are never updated. I have NO idea what the other people who give this good reviews are thinking. I live in NYC, media capital of the world, and if it doesn't work here with hip-hop and Latin stations, it won't work anywhere. If you r into Latin music the site tells you the stations are supported but when you mark a song it gives you the popular songs not necessarily the songs playing. It is very unreliable, I have yet to see it work more than 3 times, and I have owned it for well over a month. If you want to get it, DON'T. At least wait until they start working on getting the play list on point.
Example Output:
Negative
