Example Output: Positive

Example Input: Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.
Example Output: Positive

Example Input: The information was worthwhile, but I found this video to be blah and boring. If you are going to bother to make a documentary at least make it somewhat entertaining! Add some interesting visuals and use a narrator that catches your attention. Read a book on this subject and by-pass this DVD.
Example Output:
Negative
