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.

I just finished reading this book and have never been more unhappy with a book. As an aside, the author also seems to be completely confused about what was going on when certain events took place. For example many reviews here and elsewhere state that "The Battle of Guilford Courthouse between General [Nathanael Monk] Greene and Lord Rawdon is almost exactly as it happened in Oliver North's books" or some other such nonsense. Please read up on North before you write these reviews.
Output:
Bad review
