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: THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?
Example Output: 1

Example Input: I love chocolate with cinnamon in it, and artisan chocolates in general, so i had such high hopes for this product. It disappointed me.  First off, it was grainy, in a too-much-sugar way, not a coarsely-ground-cacao-way. If you break off a piece, you can see the sugar crystals glinting in the chocolate.  Second, it had almost no flavor. I couldn't taste the cinnamon at all, and the even chocolate itself was weak.  It smells wonderful, but tastes like grainy nothing.
