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

Example Input: Love the show, which for me has held up well: it's obviously dated but still makes me laugh.What didn't make me laugh, though, was the quality of this DVD. The quality of the transfer, it's as though you're still watching it on VHS! It doesn't support surround-sound, even by just repeating the two channels.There are no subtitles in any language, and no special features of any kind!Worse, mine had scratches right out of the plastic! The scene where Jack comes up to the breakfast table in his speedos is all pixelated. Was that true for anybody else?
Example Output: Negative

Example Input: I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.
Example Output: Positive

Example Input: Received DVD's with no issue. The problem was that they were formatted for a region other than the United States. This is strange to be due to the fact that they were shipped from an American address to an American address. Amazon refunded my money with no issue.
Example Output:
Negative
