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.

The Rumours DVD is a retrospective documentary made 21 years after its release. Nothing more and nothing less. It's appeal will primarily benefit those interested in the way the tracks were laid down, the underlying emotions that led to the creation of the individual songs, and hearing bits and pieces of the tracks with the other instruments removed. It's important to remember that no filming occurred in the Record Plant (their recording studio) during the sessions. The film footage that did exist was all post production concert footage; sound quality that is poor by present video based audio standards.With that said, those interested in learning how one of the most emotionally charged albums in Rocks history was created will find the DVD very gratifying. Those looking for film footage of the songs being played in their entirety will be disappointed.
Output:
Positive
