In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Example Input: Fiber one products actually don't have real fiber.  They contain inulin (from chicory root) which is technically fiber because the body can't digest it.  Unfortunately fiber is defined by anything that can't be broken down easily.  These products do not contain REAL fiber. (The real fiber usually found in whole grain breads and bran cereals) So if it says "chicory root" or "inulin" in the ingredients, you can be sure you aren't eating the fiber your body can actually use.  So if you want lots of sugar and fat without fiber, this product is for you.
Example Output: 1

Example Input: You won't find a better gluten free pancake mix out there.  As a matter of fact, I much prefer these gluten free pancakes to regular pancakes (and I buy them for my husband).  I love bisquick for this product!
Example Output: 5

Example Input: These are not only a good value (health food stores really jack up the prices on rice cakes!) but also are nicely thin and easy to use to spread stuff on.
