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 love VitaMuffins, but my supermarket sells one box of 4 muffins for $6.29.  Instead I bought the mix, 3 boxes for $16.00, and each box makes 12 muffins. Instead of $1.62 per muffin, the mix only requires water & eggs and works out to about 48 cents per muffin, and very easy to make. That's a great deal.
Example Output: Positive

Example Input: The other review is correct... artificial color has been added to a great product and ruined it. The genius behind this decision should be tarred and feathered and run out of town on rail... ok, then, just fire them. The Altoid customer base, I would imagine, prefer natural ingredients and don't want crap... this is crap. The marketing genius behind this decision canNOT be a regular user of Altoids... any regular user would have known better... don't destroy a winner to make it look "pretty". I'm eating them for pete's sake, not dating them.  Same with the Spearmint. Ruined by artificial color and ingredients.  Duh... I guess I am too stupid to know the difference... Duh.  I am still buying the Peppermint... for now. As far as I know, it is the only Altoid mint that still uses natural peppermint oil and no artificial colors... for now.  OOoh oooh... how about this, marketing geniuses at Altoid... artificially colored red stripes in the Peppermint. Brilliant! Seriously, anybody that sees this and think it's a good idea needs to be FIRED.
Example Output: Negative

Example Input: I am a Bisquick biscuit lover from way back, and I thought the biscuits made per the recipe were a little blah, but I think they would be perfect using butter or margarine in place of shortening, so I have hope. As far as the cobbler goes, I made a triple berry using the shortcake recipe on the back (which calls for butter rather than shortening) as the crust. It was amazing. If you are expecting the ease of regular bisquick, forget it. This is not a "just add milk and stir" kind of product. The biscuits require the addition of egg, shortening (cutting it in, but it is easy and not too messy to mix with your fingers), and milk. Also wish there was more in the box. Most of the recipes on the back require the use of the whole box.
Example Output:
Positive
