Input: Consider Input: I went to two stores trying to find the exact brand name products that Sandra Lee insist we use. Frustrated, I asked the store mananger who told me that the products I was looking for, Campbell's fat-free mushroom soup and Jello refrigerated vanilla pudding cups are no longer available in my area.Why make such a big fuss about using this or that brand when they aren't even available? I won't waste any more time travelling around town looking for the exact brand names needed to make the recipes in this book.I have better things to do! Maybe this book needs a "use-by " date before even more products become obsolete.

Output: Negative

Input: Consider Input: Great tunes dripping with latin up beat melodies and smooth syncopation. One track could have easily appeared in a 007 flick.Slick production and sound makes for great party music ; dancing or sitting ! "Oh yeah" will always turn an ear with or without the accompaning movie.......

Output: Positive

Input: Consider Input: I absolutely loved this book, it was so engrossing, could not put it down. Hawthorne has wonderful descriptions, it is a fascinating time in history and he brings it alive. A flawless book.
