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

Input: Consider Input: I haven't been able to watch this much because the DVD won't play in my normal (otherwise functioning) DVD player. It will play on my computer's DVD player, but without sound. The DVD will play fine on my laptop, but that's not a screen that's very conducive to practicing in front of. The DVD does play on my friend's DVD player for some reason. Also, I bought volumes 1 and 2 and both are so short, it seems obvious that they could have put all of the lessons on one DVD. I guess they knew they could make more money by making us buy both.

Output: Negative


Input: Consider Input: The adapter worked fine for my power book g4 for a few months and then it broke. Nothing physically happened to the adapter for it to break, but suddenly it just wouldn't charge any more. What's interesting is that the blue light on the brick goes on when plugged in to a power source, but if I plug the cable that attaches the computer to the brick in, the light goes out and it doesn't charge.

Output: Negative


Input: Consider Input: I bought two sets of these. They're priced at $9.50. But, when they arrived, the price tag still stuck on the item says $2.99. Nice way to hide your "shippign cost" ($6.51) from your customers! This company goes on my "Never Again" list!


Output: Negative
