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

Input: Consider Input: This is being written mostly in protest of the re-print. The stories in these series were always a little dull. But the art, the art was fantastic, and now they've taken it away. I dont have my old copies any more and now the old books are going for outrageous sums. I wanted to get these books for my kids someday--not any more.

Output: Negative

Input: Consider Input: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.

Output: Negative

Input: Consider Input: Every year I think we get going too quickly and make an impulse buy that's foolish. This was our purchase this year. Thankfully we got a 50% credit for making the purchase (not sure what promotion it was since I didn't see it) and we got $1 toward Amazon MP3s. So our foolishness was credited, but before you buy this always remember that it airs on tv every year (in our case 3 days after we purchased it). If we had checked our TV guide we would have seen it and been able to record it for free. Buyer beware.Don't buy it.
Output: Negative
