Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I love all of Sophie Kinsella's books and her writing style...but this book was awful. The story line was predictable and the writing flat and unoriginal. Makes you wonder if this was truly written by Kinsella or a way for a ghost writer to get started under her 'new' pen name. I don't plan on buying anymore Madeline Wickham books--stick to the original Kinsella, where I haven't been disappointed yet.
Output:
Negative
