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: These are great because they're only 100 calories per pack and are just as good, if not better, than other chips out there. The "Original" style taste exactly like Munchos, but don't come with the high calorie count. The other flavors (Sour Cream & Onion, Salt & Vinegar, Salt & Pepper, Cheddar, and BBQ) are all delicious, as well.
Example Output: Positive

Example Input: Oh my gosh, is this good! Like most people, I've been eating ketchup my whole life and never really thought anything about it. Then Hubby brought a jar of this home. The tomato flavor is amazing. I will never buy store ketchup every again.
Example Output: Positive

Example Input: Can't tell you how this tastes, because I read the ingredients first, but it has trans-fats in every flavor. :( The seller should disclose all ingredients in the description. I wouldn't have purchased this otherwise.
Example Output:
Negative
