Example Input: The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.
Example Output: Negative

Example Input: I was extremely lucky to have found this, because it is a) an import & b) limited edition...especially lucky to find just thrown in the kylie section of a Pennsylvania Borders! Ok, here it is track-by-track:1. Chocolate [Radio Edit]:While this cuts the album version of the song by one minute and two seconds, it's better. Her vocals are improved, & more of an arrangement is used. 10/102. City Games: THis extreme rarity is fabulous. Very R&B; pop. 10/103. Chocolate [Tom Middleton Cosmos Remix]: A club dub. Cool when you have so much energy in you that you have to dance it out, but not for a regular listen. 7/104. Chocolate [EMO Mix]: Woderful. A good R&B; dance mix of the song. 9/105. Love @ First Sight [Live]: A live version of the Fever hit. I usually love live sounds, but this when isn't quite up to par with the original. 8/10I still have yet to figure out how to access the video. (...)Overall great package, great mixes, great rarities.
Example Output: Positive
