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: Save your money and do not buy this product. Does not even come close to bacon flavor more like a hickory smoke taste. After everyone in my family tried it we all agreed it was nasty(we're not picky either).
Example Output: 1

Example Input: I had high hopes for the convenience of this product.  My daughter LOVES hot chocolate. This really was a total disappointment.  I threw these kcups out.  If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate.  Larger settings are not drinkable.  Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.
Example Output: 1

Example Input: Tastes like darjeeling, although, like one of the previous reviewers said, it's missing some of the body of a good darjeeling. I give it 3 stars for taste alone. But for the price I paid for it, I guess it's still a solid deal  You get what you pay for and for the cost of this tea, I guess it's good. :)
