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: I was disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.
Example Output: Negative

Example Input: Love the pineapple flavor. Makes me feel like I am on vacation drinking a pina colada. (You probably could add a little rum and.....)Really tastes better than other pineapple coconut waters I have tried!!
Example Output: Positive

Example Input: I tried this before having normal red tea so I waited to review. The flavor still rings in my head it is earthier than rooibos tea and less frity. The color is that of muddy water, and it has the grittiness and viscosity of it as well. Well worth every penny.
Example Output:
Positive
