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: I don't like using artificial sweeteners because of the chemicals and because they don't taste good. I am a caregiver for my diabetic dad, and once I discovered this product I was hooked, except that it is hard to find where I live. When I found it at Amazon I put it on auto ship so I don't run out.  The price has gone up a lot since I first found it on Amazon, however, it still costs more in stores if and when I can find it there. I make limeade with this which I keep on hand at all times. In a gallon container of water I add 1 cup of lime juice and 2tbsp. of stevia powder. It is refreshing and almost no calories and no chemical aftertaste.  My dad uses the stevia in his coffee and his oatmeal. I haven't tried cooking with it although I know they make one designed for baking, which I'll possibly try this winter.
Example Output: 5

Example Input: I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.
Example Output: 5

Example Input: I really love this coffee, great tasting and bold.  However, on about 1/3rd of the pods, the foil separates from the cup and blows grounds into the brewer and my coffee cup.  I can usually predict which ones will do it because the foil on the k-cup is not puffy like it has pressure, but flat and wrinkled.
