Instructions: 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.
Input: I bought this based on the rave reviews posted previously -- but one of the main ingredients is MSG. There's gotta be a way to make a good BBQ rub that's not loaded with the stuff, which gives me and my wife nasty headaches.......
Output:
Negative
