Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.
Example Output: Positive

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: Three lovely young ladies all want Elvis' gearstick in this craptastic musical comedy that's so bad it ROCKS! I just love the title song sequence where Les and the guys 'provide' Elvis with "...lots and lots of girls." And who was that chick, the blonde with the short cropped hair who literally shoves all the other chikadees aside to get up and spinout with the King? She looks like she's out to prove she can really score, and I never saw parts move like that before! Elvis looks embarrassed. Anyway, after you've crossed those double lines and Spinout you will want to do so again and again and again. Simply awful, but I mean that in a great way.
Example Output:
Negative
