Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I'm not any sort of expert of musicals but all I know is I really enjoyed this when it came out and years later I still find myself whistling Evita songs every other day. It is memorable music and this movie/soundtrack is done in a very entertaining way regardless of how faithful it is to the original. The story itself is good but ultimately doesn't really interest me and I'm not a fan of Madonna or Antonio Whats-his-name, and Latin American politics isn't the most fascinating setting for a story, but dammit...this is just a good soundtrack and rarely is a story ever told so well with such a diverse array of music. Plus unlike many soundtracks that skip songs this one is literally THE sound track to the musical. I pushed play on the CD once while the DVD was playing and it was synchronized.
Solution:
Positive
