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

Example Input: Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
Example Output: Positive

Example Input: If you're willing to trade a little style for some substance and save some money in the bargain, this is a very recommendable device. My Apple PowerBook power supply died in what is apparently typical fashion - sparking, crumbling wire where it meets the brick - and none of the Apple stores or CompUSAs in Atlanta had any in stock (which is curious in itself). I resorted to Amazon and decided to try this one out and I've been pretty happy with it. It seems sturdily constructed, and the breakaway cable is a surprisingly handy way to save on tangles. I do miss the plug-in charging light, but that's about it.
Example Output: Positive

Example Input: Yes, you get lovely views of Tuscany and yes, she is renovating a run down villa. Otherwise, it is pretty much a new story. For those who loved the book, just make that mental adjustment and start with a fresh slate and you will enjoy the parallel blossoming in the movie of the woman and her house.I took off one star since it put my husband to sleep, but I found it a pleasant enough romance with good scenery. The main character is lovely and the various subplots such as the Polish laborer romancing a local girl expands the story to pull in the younger audience, I presume.
Example Output:
Positive
