Example Input: If you did not know it starred a very young Mel Gibson, you would have never believed that it was really him. This movie was a really good revenge movie. The only problem I had with it was trying to make out what was being said. It is done in "Australian language" and, though it is basically English, the accents of most except for Mel Gibson's character are so strong that you really have to over-listen to try and figure out what is being said. Other than that, the movie was a good movie and the crash scenes were fantastic for the era in which it was made. I only wish I could have understood what everyone was saying without straining in order to get even half of the dialogue. But, it is a movie well worth viewing.
Example Output: Positive

Example Input: Cities Of The Red Night is one of the most enjoyable books I have read. The novel has different storys that as the novel progresses intertwine. The books presents situations that are unbelievable but because of Burroughs genius you are convinced of that they are happening in a world not too far from are own. I think he was trying to show the questionableness of what is presented to us as reality. This book also has some of the most vivid pictures and unforgetable lines that I have read. It is Burroughs masterpiece.
Example Output: Positive

Example Input: I buy/view/listen to a lot of music video's (read, sorry night life) and this one was a disappointment. Sound varies too widely act to act. Couple of goosebump moments (I love the Mega-Guitars on Kansas City) but mostly a smorgas-bored of available talent putting in their charity work. Zero additives for the video freak and no real explanation of charitable intentions ever given. Borrow this from someone instead.
Example Output:
Negative
