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: Short and sweet.....The product itself is top notch and my two GSD's love it. However, the last shipment looked like it was packaged by a three year old and thus it arrived via UPS with a can lid popped open spilling its contents over the other dented cans. Another case arrived seperately which was properly packaged using air pillows and was fine. Don't get sloppy Amazon. It will cost you customers.
Example Output: 3

Example Input: My son and daughter-in-law told me about these chips and they purchased a few bags at a store and I will say they are higher in stores then you can get them online on Amazon. They brought me a bag and I was hooked! So I ordered popchips online and they are the "BEST" chips!! There wasn't a flavor I didn't like or that my family didn't like. I am a (chipaholic) and these are better for you and a great tasting chip. I highly recommend these to anyone that can't do without eating chips either with a sandwich, hamburger, or just to munch on midday. You won't be dissapointed.
Example Output: 5

Example Input: Personal preference... too sweet.  Tastes like General Foods International Coffees.  Price is great if you like that, though.  And makes up very easy.
