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 bought this item when it was heavily discounted (about $12) and it got here very promptly, since I am a Prime member. Every can has small dents. The discounted batch I ordered and recieved appears to consist entirely of factory rejects. They were bought 02/2012 and have a 12/2013 best by date, so not that big of a deal. None of the cans are punctured, just small dents. The contents are currently GTG.  I'd say if you are planning on eating these within a few months to a year or so of purchase, go ahead and do it. If not, I wouldn't trust dented cans beyond their best by date, or even really too far before then.  As for the contents, same as you buy in the store. Wife and kid love them, which is why I bought it.  The price has more than doubled since I got mine. Perhaps I just got a reject buy... Be warned.
Example Output: 3

Example Input: I will never understand the soaps from mainstream, and sometimes otherwise great brands, who claim to have a line of "sensitive skin" products which still contain Sodium Lauryl or Laureth (as in this case) Sulfate. If you're someone who needs sensitive skin products there's a more than decent chance that you also need stuff without SLS. Boo. Refer to their bar soap, which is wonderful.
Example Output: 1

Example Input: I have been using this curry paste for several years now, and it makes a great dish. Although it doesn't beat eating Indian out, its the best paste I have used for at home dishes. Even though this is a "hot" paste, I would consider it mild.
