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: I found it much tastier than the plain tuna pouches out there. Excellent quality, and no need to 'dress it up'.  I put it the micro on about 20% power for 1 minute and Shazam!  I believe a little heating brings out the flavor.
Example Output: Positive

Example Input: This review is from my wife:  "I'm not one who has all the right words for describing taste and flavor, unfortunately.  I say "unfortunately" because this is a very good tasting coffee and it deserves elegant description.  What I can tell you is that it has no edgy bitterness.  No bitterness at all, actually.  It's rich and smooth.  Yum.  I use a European coffee press for brewing and this grind worked beautifully in that.  Not too course, not small enough to make a mess through the screen."
Example Output:
Positive
