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

Example Input: This one doesn't really fall into the Western category, but it's full of hammering action, informative local California history, and mystic goings-on. Seacoast adventures, early Califronia ranching, great good-guys and really bad bad-guys, and mysterious appearances by silent, unknown characters fill this one to the brim! Best of all, L'Amour introduces in this story, for what I believe was the first time in his writings, the famous "portal to the other side," which really sets this story apart from almost all of his other works. Excellent yarn through and through. You won't forget it for a long time after you first read it!
Example Output: Positive

Example Input: Only has limited access to OBDII data stream unless you pay more money to upgrade the software.
Example Output: Negative

Example Input: Mad Max and Escape From New York are two titles I would consider essential to have in my BD collection, but I will not be buying them in their present state. Why, you ask? Let us do some simple science and maths:Science in the sense of positing a fact: I watch all my discs on a 50" plasma television, and listen to them with a receiver that decodes 7.1 channel lossless soundtracks via the HDMI ports.Hence, Blu-ray + DVD = NOT GETTING MY MONEY.It really is that simple, MGM and anyone else who is contemplating force-feeding consumers what I now refer to as a holdback format. I have already imported Alice In Wonderland and Iron Man 2 from Amazon.com because the locals tried to force me to buy a DVD. So when the UK Amazon offers Mad Max and Escape From New York without force-fed DVDs, guess who is getting my money?DVD is dead. Face up to it. It died the day that BD spoke up and offered us the experience of progressive television.
Example Output:
Negative
