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: This is a great product.  We tried it at the beach the first time and loved it.  The cashew crunch was not as good. We bought a case of the almond this week.  Just great!
Example Output: 5

Example Input: My father could no longer take care of his beloved 6 year old Cocker Spaniel, so I decided to take her into my family. When I brought her to NYC she had ear and eye discharge. She was also  slightly overweight. After a check up with a vet that ruled out infection, I decided to try Royal Canin based on the numerous good reviews.Within a week her ear and eye problems were gone and she dropped a good amount of weight. This is going to be the only food that we will be feeding her!
Example Output: 5

Example Input: Thought these were the larger sized ones you see in stores but I was mistaken.  These pops are about 7" inches long and a little less than 1" inch wide.  Flavors are comparable to Flavor-Ice, not necessarily better.  My wife and I enjoy these throughout the year instead of ice cream, but we can only find them in our local grocery store during the summer months.  Glad we can get them via Amazon! These were on sale for $5.48 per box of 100 with free shipping, so I think we got a good value.  Without the sale pricing, I'm not sure if we'd choose these over another brand, but if they do go on sale again, we would probably buy them again.  Not bad, just a little small...  Eat two!  ;-)
