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: Wow, I did a lot of reading trying to make a good decision on a K-cup hot chocolate, and of course taste is something that is very subjective.  If you read all the reviews on every product you'll discover that nothing gets past everyone and maintains a perfectly spotless reputation.  So I decided that even with some bad reviews I'd try this one since it has a lot of good reviews.  I'm just going to say that there are some real hot chocolate connoisseurs writing reviews in this thread.  Some discerning reviewers say it has a slight taste of sugar substitute, or some such thing.  All I can tell you is I must have under-achieving taste buds because all I can taste is yummy hot chocolate.  My family burned through the first box and I just ordered two more.  If you don't like this I feel sorry for you. Better to have numb taste buds I guess.  Enjoy.

Example Input: I'd been hearing about the product for a couple of years and finally ordered some, but inadvertantly ordered lite! Yuk! After much anticipation, waiting for it's arrival, and then finally opening up the (cheap plastic) jar and putting some on a piece of bread to try it with.... it tasted like wall spackle. Ok, I've never eaten wall spackle, but I'm pretty sure it tastes like "lite" baconnaise. Then I realized after careful examination of the label that I ordered the "lite." Dammit.  Determined to finally taste the ORIGINAL baconnaise, I went back on amazon and (very carefully) ordered the ORIGINAL baconnaise. And it's pretty dang good! I'll leave a review of the original, non-lite product there.
