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've bought these at the local supermarket and enjoyed them although they are so salty that a few leave my tongue and roof of my mouth burning.  Keeps you from eating too many!  Occasionally I get really stale items from Amazon.com and this was one.  Unedible.  Beware of the quality of food items on this website that are on special as they can be very close to due dates or in this case, not expired but stale and unedible just the same.
Example Output: Negative

Example Input: This taffy is so good.  It is very soft and chewy.  The flavors are amazing.  I would definitely recommend you buying it.  Very satisfying!!
Example Output: Positive

Example Input: Tortilla soup is one of my favorite soups, and I like both the tomato and chicken broth varieties. Although I didn't expect freshly fried tortilla strips or queso fresco in a canned soup, I did expect something that resembled all other tortilla soups I have tried, that is a LIGHT broth with a mix of vegetables, corn, beans chicken and Mexican spices. This soup is thick - really thick, like the thickest tomato soup you've ever had with a grilled cheese sandwich. It's also sweet, and does not taste in the least like a Mexican soup. Instead, imagine straight tomato soup with a bunch of vegetables, beans and some chicken thrown in.  I ended up giving it all away, and, to be fair, one of the people I gave the soup to said her husband really liked it.  For a canned soup that much more closely resembles real tortilla soup, try <a href="http://www.amazon.com/gp/product/B0014EUB7I">Campbell's Select Mexican Chicken Tortilla, 18.6-Ounce Cans (Pack of 12)</a>.
Example Output:
Negative
