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 Output: 5

Example Input: I purchased this as a present but it doesn't come As shown in the picture.  It is little white bags with the flavor written on them.  Someone receiving it as a gift wouldn't even know what it was unless I explained it to them. Will be returning.
Example Output: 2

Example Input: It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.
