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 am a fan of Dan Brown and his books, but "Angels & Demons" just didn't make it. There were many loose threads to be wrapped up as well which ended up left dangling. Why did Angels have the gift of telekinesis? Who was Mallozzi? What does he really know? Etc. etc. The big mystery at the end is never solved either, except for in Brown's own head (which got so tedious after a while).
Bad review

This product seems to be very high quality and I am happy with the purchase. But it is bigger than a regular mug size. The cover makes you go around in circles just as much on your car windows if that helps any? :)
Good Review

I purchased these in September 2012. Last night it happened. The left ear piece broke.
