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 pretty good regular style soy sauce.  But it is not super-wonderful-better than any other good quality soy sauce you can buy in an Asian market.  The main value is as a unique gift.   In the Japanese soy sauce world, there are 4 types: regular, mild (usukuchi), for raw fish (sashimi) and light colored.  Bluegrass soy sauce is regular style.  Compared to Kikoman (a good commercial brand that is widely available) Bluegrass starts saltier, is flat in the middle, then ends with a complex & interesting flavor.  Kikoman is less salty initially and has a round, full flavor in the middle.  Doesn't have the complex ending flavors.  For me, the initial saltiness of Bluegrass is a minus and Kikoman's full middle flavor is a plus.  I prefere Kikoman, especially for dipping sushi where the flavor is more direct.  But I lived in Japan for many years and am used to the standard Japanese flavor.  I haven't tried Bluegrass blended in other food as a background flavor, which is how soy sauce is usually used.   Bluegrass is a perfectly good soy sauce.  Each brand has a different flavor and everyone has their favorite.  If you want a unique Kentucky gift for an Asian friend, this is different than the standard bottle of Bourbon or box of chocolate.

Example Input: This stuff is pretty solid. Makes a decent enough pancake for being GF and makes a solid biscuit as well. What we have found works best is taking this mix and using it half and half with the Chebe mix. Between the two it makes for a very nice flour mix. The Chebe is good but on its own tends to be a little squishy, but when you mix it with the bisquick, the bit of squishiness gives the dryer Bisquick the fluffiness and moistness it needs. So, I recommend this, but I would HIGHLY recommend getting some Chebe too and cutting the Bisquick with it. Also, even though this mix has leavening agents in it, when we use recipes that call for leavening agents we add them anyway, it tends to turn out better this way.

Example Input: The Sugar was sweet, that can not be denied.  As advertised, It didn't melt when baked either.  However, it will not do for your Liege Waffles/Gaufres what the larger pebbles of Belgian pearl will do.  These grains are smaller, think pretzel salt, or seed pearls.
