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: Of the few Hot Cocoa flavors we've tried, this is the best so far.  It has the richest flavor and I dont notice the artificial taste that others have commented on.  Its also very affordable compared to other k-cups right now.  I thought that the k-cup making process must have gotten more expensive over the last year, but now I know they are truely sticking it to us since these are still reasonable priced.
Example Output: 4

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.
Example Output: 1

Example Input: Plocky's Red Beans and Rice Tortilla Chips are really tasty. I shared a few bags with my daughter in Iraq. She said Ummm they are Good. They are good for you too. No artificial stuff.
