Example Input: If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!
Example Output: Negative

Example Input: I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.
Example Output: Negative

Example Input: Why on earth would anyone give this movie three and a half stars (out of the traditional four star system)? I kept watching this tedious film, hoping that perhaps the answer might be found in the next scene. This is a confused, jumbled mess. It's an unintelligible, incoherent, impenitrable story that makes absoloutley no sense and goes from nowhere to nothing. Each scene seems to have nothing to do with the one before or after it. As best as I can figure it out, it's a wierd cross between "Duel" and "Death Wish", but no where near as good as either. The action is disappointing too,unless you like seeing vehicles getting wreaked.
Example Output:
Negative
