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

Example Input: I teach The Odyssey, and let me tell you, this movie does NOT reflect the book well, if you're watching it for testing purposes (and I know you are!) However, I DO show selected scenes (out of sequence because the movie is out of sequence) just because my students think it's fun. WHEN will a GOOD version be made??? I had such hopes for Troy, and meh....My students' favorite part is the inexplicable arm action of the guard who announces "Tele-machos of Ithaka!" Scenery WILL be chewed - even the usually OK Greta Scacci comes off rather poorly.
Example Output: Negative

Example Input: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.
Example Output: Positive

Example Input: I was really distraught to go to my local Walmart and see that they stopped carrying my favorite cereal. But as was elated to find that "the site who has everything including a church" made it available to me by the 6-pack. Oh's is an amazing cereal. The one thing i dont like is the box is so small. I get maybe 3 bowls out of the entire box:-(.
Example Output:
Positive
