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 found this tape very disappointing, it was fun to watch once, but the amount of information provided was very small and too choppy. There are many belly dance instructional videos available which are more interesting, better taught and more informative about how to dance and which provide you with a workout as well. My recommendation is to keep looking.
Output:
Negative
