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: These are my favorite, but they aren't for everybody. In a way, they sort of taste like Oriental flavor ramen, but with a kick. For me, how can one go wrong with the combination of jalapeno and ginger? They are a bit rich, so they aren't for EveryDayForAMonth snacking. Because this is a case purchase, I recommend trying out a single bag before buying an entire case. The 2oz size seems to be no longer available, which is a shame; I can eat the entire 5oz bag.
Example Output: 5

Example Input: Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>

Example Input: There ought to be a recovery program. But the good side is that a Mrs. Mays addiction is healthy. I already have a stack of boxes in the garage so I won't run out. And here I am stockpiling more (in case of nuclear holocaust).  Almonds have always been my staff of life -- raw, roasted, dry roasted, blanched, flavored, and of course Mrs Mays. I rarely have a day without them. I even feed them to the parrot. A bird guy told me they were the healthiest. And the bird goes nuts for Mrs. Mays.  These are, dare I say, miracle nuts. One taste and I was hooked. How she can pack all that goodness into such a tasty snack with such healthy ingredients is a miracle. If you're tired of tastless, bland, gotta-eat-it-because-its-healthy snacks from the nutrition store, try these for a pleasant awakening.  Mike
