Definition: 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.
Input: These don't work at all. When my computer tries to detect an audio device the product does nothing, which makes them completely useless as advertised. This is in no way due to their faults: both units malfunctioned in exactly the same way.
Output:
Bad review
