Example Input: I really love the way this TV looks but my LCD and HD channels have a green tint on them. In addition, every channel has digital artifacts in it. Very disappointing. It's an older LG so it may just be quality that varies from model to model. Too bad as I've had luck with their products. : -(Now if only they would fix those issues because of this TV's price...I will return it. Edit: 11/2013 -- This is not what was promised.
Example Output: Bad review

Example Input: i did not enjoy this book at all. it was pretty boring. the only part of my interest in reading and finishing is finishing what we started. unfortunately, it didn't come together for me.
Example Output: Bad review

Example Input: While I really like this case and was excited to get it, it does not offer much, if anything, in the way of protection for my camera. The top is exposed only enough so that you can access all buttons as they are covered with hard plastic flaps which covers them completely. You don't have any options for connecting cables or cords either. It should be a little bit bigger because now it's basically useless since nothing fits inside.
Example Output:
Bad review
