Example Output: Positive

Example Input: Although the music of this CD was just what I needed to teach a lesson on early jazz and it's influence on the artist, Mondrian, I was disappointed that it did not have the cover sheet shown or any information about the artists. The CD package was broken.....Other than that, it was fun to play it as the children in my art class painted their own version of"Boogie Woogie Broadway" by Mondrian.Art Specialist --- Las Vegas, Nevada
Example Output: Positive

Example Input: You figure zombie movies have been out for at least 20 years and to this date we still can't produce a low budget zombie movie with better actors. The dialogue was good the presentation sucked. it was like they were reading the dialogue instead of experiencing it. The plot was good as well. This movie had all the elements of a well made zombie flick but no one was chomped only the token Lesbian Black chick. Good try but I wanted more.
Example Output:
Negative
