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: We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.
Example Output: 5

Example Input: I just received these bricks today and was very disappointed to find that BOTH of the bricks were broken and unusable as a serving/cooking plate.  They were busted completed in half. They were packaged in one sleeve of small bubble wrap in a shallow box with no other protection or packaging in the box.  I went online to try and return them and they are not eligible for return.  This is the first return I've ever tried to do in over 7 years of purchasing items off of amazon (to the tune of several orders a month!) and yet the one time that I want to return a defective product, I can't do it.  I will be much more careful about what is eligible for returns and what isn't in the future.
Example Output: 1

Example Input: Best Bit-O-Honey I have ever eaten. I have always bought this product at a local grocery store and it was always hard, I figured it was suppose to be that way. But after eating the box I bought here I now know better; the candy was soft and delicious. I plan to continue buying Bit-O-Honey from here.
