You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: Chips are not as tangy as I hoped or expected. Poore Brothers is a better choice for the "hard-core" Salt N Vinegar fans.
Example Output: Positive

Example Input: These chips are pretty delicious.. Even the original flavor with nothing on it is good. It's not as delicious as Doritos, but it's also not fried either, which definitely balances it out. A good snack for all times of day!
Example Output: Positive

Example Input: Someone brought these to a party we had last month and I didn't put them out because the buffet was full and didn't think anyone would like saltless potato chips.  Last week we had some friends over and these were all I had in the pantry so I put them out.  OH MY GOSH THEY ARE SO GOOD!  I was so wrong to think they would be bland; they are full of real potato flavor, wonderfully crisp and very fresh tasting.  I am here on amazon to buy a case, I only want to have these with dips.  Truly delicious!
Example Output:
Positive
