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 like the dried peas from Just tomatoes and I also like their Just Corn.  They are way too expensive though.  They are really handy because I don't use frozen or canned foods because I follow an Ayurvedic diet which prohibits them.  When I can not find fresh peas I have to use these.  I will probably have to do without as I can't afford these, too bad.
Example Output: 3

Example Input: These truffles are not as great as they are made up to be. I thought for the price they would have a greater taste, but they didn't have much taste at all. They are not worth the price, but had to find out for myself. I will not be buying truffles again, and I'm not going to spend over $10 for a fresh one.
Example Output: 2

Example Input: Great price for what you are getting.  Recording via a USB port ROCKS!!!! The only thing that could maybe be improved is the durability.  It feels like a toothpick in your hand.  It may be more durable than it feels, but I'm still going to be very careful with it.  But, for the price this is only a minor gripe.  Great product, I would recommend it to anyone.
