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 really liked this flavor!  As someone with many food sensitivities who also avoids sugar, this is the perfect treat for me when I crave chocolate or baked goods.  The raw nuts are crisp and fresh tasting.  However, the price was very high for the quantity of product.  With less than 20 brazil nuts in the package, I felt a little gipped.  In future, I'll try making my own chocolate nut mix from bulk raw nuts, berries, and coco powder rather than spend $9 per package!  For that price, I'd like a lot more product.
Example Output: 3

Example Input: I thought I was purchasing a high quality item but it's not all that. The chocolate is very sweet and as you chew on this product you can tell the chocolate is loaded with sugar by the crunchy texture. I'm going to say it's not worth the money and I'm not satisfied. At the same time of purchasing this product I also bought Sunmaid chocolate covered raisons which I rate from a 1-10...a 10. Now we are talking about yumminess!!!!! So customers...if you are going to choose...let it be the Sunmaid...you won't be dissappointed
Example Output: 2

Example Input: This product does not smell very well to me.  In fact, I have to use a fork to "tenderized" the pieces for my old kitty cat.
