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 was one of the worst books I have ever read. The plot is hard to buy and not well developed at all. It had way too much sex - who cares whether they are a couple or not, really. Save your money. It's terrible.
Output:
Bad review
