You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Flat lighting, cheap sets and costumes, dull dialog, wooden acting, and a goofy plot; even pervasive silicone enhancement can not save this movie. Zero stars should be an option. For more inspired soft porn, check out the work of Andrew Blake (andrewblake.com).
Output:
Negative
