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: It's a refreshing drink when served cold. A bit sweet when warm. A little tart, but tolerably so.  The flavor is less orange than tangerine, yet I can distinguish several different "layers" of citrus in it, including the orange. It's an interesting sensation.  I am a little bugged by the fact that an 8.3oz can (2/3rd-size) manages to pack more junk calories in than a full-sized can of cola. It's also supposed to be 100% juice, but reconstituted grape juice is practically pure sugar and there are "natural flavors" noted in the ingredients list as well as a soy warning which to me implies some sort of MSG, probably added with the citric acid.  So, maybe it's not an especially healthy beverage. It's still tasty and provides a diversion from more typical sodas.

Example Input: Of the 12 cans shipped 11 of them had very, very serious dents in them. I'm not talking dings, I talking serious dents.  So dented that I truly thought of throwing them away.  My husband stopped me though because at $5 a can he felt that it was too wasteful.  In my local grocery store, items this dented are put into a reduced price bin, because they usually don't move otherwise.<a href="http://www.amazon.com/gp/product/B002C4HZ00">Cento San Marzano Certified Tomatoes, 28-Ounce Cans (Pack of 12)</a>

Example Input: These are to potato chips as Pringles are to chips; as instant coffee is to brewed coffee; and Stephen Baldwin is to Alec Baldwin - same family but scant resemblance.  So I'd buy a single, small package at your grocers and try them out.  Not for everyone, and certainly not for my family which includes two teenage boys.  Even they take a pass on these unless they are truly desperate.  Crispness is OK.  Even mouth feel is good, but there is a lingering (not good) taste - again, kind of like Pringles.  PS: the flavors are OK but definitely taste like they were made at that flavor factory along the Jersey Turnpike.
