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

Input: Consider Input: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.

Output: Positive

Input: Consider Input: Thia is the saddest story I have ever read! Poor girl---she doesn't have a chance with finding a happy life! The cards are all stacked against her from the git-go!

Output: Negative

Input: Consider 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.
Output: Negative
