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: I love Cherrybrook Kitchen and have tried almost all of their products.  I was excited to try the Ready to Spread frosting, as I do not usually keep the needed ingredients on hand for their box frosting.  I am not a picky eater, especially if the item contains sugar... but this was horrible!  The consistency is absolutely nothing like regular canned frosting.  It is not light and fluffy.  It is very gooey.  I cannot even imagine trying to spread it on a cake - it would rip it to pieces because it is so thick and gooey.  I did not even try it on a cake, because the taste and texture were so off-putting.  Seriously, do not waste your money!

Example Input: Fortunately, before I purchased I read through enough reviews of these k-cups to discover that they add some artificial sweetener to them along with sugar.  I'm shocked that the item descriptions don't make this clear.  I consider that important information!  I decided to give them a try, anyway, considering some reviewers thought it was hard to tell.  I realize that many products do this recently, but they usually fall short of hiding that nasty aftertaste.  Sadly, this one does too.  It's close - I can almost enjoy a cup - but it's still unmistakable, especially if you don't consume much artificial sweetener.  (I chew sugar-free gum, and that's it for me.)  It's a shame, too, because the chocolate flavor is nice.  In fact, I rated these a 3 simply because my son tolerates the sweetener enough to drink them.  And I was really jazzed about the caramel cappuccino before I found out about the sweetener...but now I won't be buying any.  (Side note: many cappuccino reviewers complained that they're instant coffees that taste like gas station cappuccino - that would be fine with me, if it weren't for the artificial sweetener which those gas station cappuccinos don't have.)  If they begin to offer a line without the artificial sweetener, I'd buy it, but until then I'm staying away from Grove Square products.

Example Input: A really great Sauce but is slightly more expensive than in other stores. It is great for egg rolls or a dipping sauce for many chinese foods! It is also a great sauce to make Chili Thai sushi roll.
