Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.
Example Output: Positive

Example Input: This is one of few films I've seen that has such a perfect combination of acting, script, photography...story. It is intelligent in a way very few films are, and treats the viewer with the respect to draw their own conclusions about this complex moral/ethical/cultural dilemma. Like real life, it shows the four-dimensionality of existence. For me as a Scandinavian-American, every emotional note rang true. Wonderful movie.
Example Output: Positive

Example Input: At 60 pages,this is over-priced and not a course for adults. As basic instruction for those 10 and under, it is probably okay. For anyone who even doodles while talking on the phone- forget it!
Example Output:
Negative
