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.

The sound is not so bad. It serves its purpose. But I only paid $19.99 for it, and it sounds that cheap. Would shop around next time.
Output:
Bad review
