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: This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.
Example Output: Positive

Example Input: This model may be ok for sedentary types, but I'm active and get around alot in my job - consistently found these stockings rolled up down by my ankles! Not Good!! Solution: go with the standard compression stocking, 20-30, stock #114622. Excellent support, stays up and gives me what I need. Both pair of these also tore as I struggled to pull them up all the time. Good riddance/bad investment!
Example Output:
Negative
