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 Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
Example Output: Negative

Example Input: Ras el Hanout is a versatile Moroccan spice blend that can be used for marinading meats (with a little oil and vinegar, maybe some crushed garlic), making stews, or just mixed with olive oil (and maybe a little crushed garlic) for dipping bread.  You can find many recipes that use it with a google term like "ras el hanout lamb recipe".  Note that it is sometimes spelled "ras el hanoud", so you can find even more using that.  I first found this at the famous (and expensive) spice market in Istanbul.  This blend from Angelina's is nearly as good.  Note that there is no one recipe for this spice blend, and there are many private recipes with a good deal of variation.
Example Output: Positive

Example Input: Had no taste and after the heat of the dish it was on turned them to a leathery tecture. Better off buying the high price truffles.
Example Output:
Negative
