You will be given a definition of a task first, then some input of the task.
Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

This is by far, the most disturbing movie that I've ever seen. For an avid horror fan, when all of them come out, even something as bad as, "The Haunting" or "Carrie", it's hard not to be disturbed but also entertained. And yet, after viewing "Flatliners", you will find yourself completely disturbed.
Output:
Bad review
