Given the task definition, example input & output, solve the new input case.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: I am really enjoying this DVD. It answers everything you need to know and makes me feel like I know what to expect when the big day comes! I have watched this video over and over by chapters and take notes simply because it's hard to take in so much information at once. What made me happier was to see the couples in Sheri's group get together for a reunion after they had delivered. I would have liked to hear the couples experiences in delivery, though. I appreciate a light and easy going environment and attitude as she teaches this video.
Output:
Positive
