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: You can find this 6-pack for $40 dollars less at diapers.com.  No reason they should be charging this much.
Example Output: Positive

Example Input: Received product timely.  Upon opening product found weevil infestation. Put product in freezer to kill weevils.  Returning product would have been a nuisance.
Example Output: Negative

Example Input: I made cupcakes with the vanilla cake mix.  They were just ok.  They were dense, but not overly so.  So that wasn't too bad. The flavor, however, is where I was disappointed.  The vanilla flavor was so subtle that I missed it entirely, and I felt like there needed to be a little more sweetness (which probably would have also made them a bit more moist). The child I made them for only ate a few bites.
Example Output:
Negative
