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

Example Input: Romantic, full of action and rich dialogue and imagery, this series will last forever (despite the epic fail of the Disney movie).
Example Output: Positive

Example Input: On a number of occasions, it had been suggested that I read this book, and I must say I'm very glad I did. I got very involved, as the writing was so wonderfully descriptive. Having said this, I don't think it was arduous to read all that detail, which sometimes makes reading a book feel a bit of a chore. I would recommend it to anyone!
Example Output: Positive

Example Input: Best Part? Nice Girth (unusual for a rabbit). Worst? Length. I find it too short. And the "off" button has stopped working (maybe it wants to keep going and going and going? *L*) I have to untwist the bottom pannel and loosen the batteries to turn it off.Overall it's OK. It does what its supposed to and has worked out OK for the shower, but I'd like to find something similar (but a little longer) for the shower.I also find the head to be a little too stiff, it should be made of something just a little softer.
Example Output:
Negative
