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.

For a fan of the old wood and fabric fighters of WWI, this film causes nothing but heartburn. The CGI effects are painfully bad, so obviously fake that it hurts to watch. And the scenes where they use actual airplanes, or recreations, are just as bad. What really bugged me was the fighters with fixed radial engines, rather than the rotaries they should have had. Forget about this film, and just read "Winged Victory" for the story by somebody who lived it. If you want to see the real airplanes fly, go to Rhinebeck, NY.
Output:
Negative
