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.
One example: The sound seems really good but sometimes it cuts in and out which is annoying. You have to put the cord directly into your ipod. Other than that, its a simple design with nothing fancy. I love how cheap they were for 10 dollars... But overall nice design... No one can steal me earphones. lol thanks again amazon.
Solution is here: Good review
Explanation: Here the review is good because it has positvie tone as the reviewer suggested it really likes the sound and the output is also Good Review.So this example is positive example

Now, solve this: This book is OK, BUT it's missing page after page of text. I bought this hoping to see it all in one place. But the Kindle version does not contain very much text - you have no choice but scroll on every page, and that often jumps from section to section, etc. So instead of being able to, say, quickly skim through section A when I'm ready for a discussion about chapter II, or maybe skipping sections where other authors do this, you'll find yourself flipping pages as you're forced to.
Solution:
Bad review
