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: Love, love, love these crunchy little treats.  They remind me of "Munchos" but without the greasy tounge afterwards.  I don't usually like flavored snacks, but these are all great, not overwhelming and no gross aftertaste.  I subscribe to them so I will never run out:)
Example Output: 5

Example Input: There isn't much to say about this mustard other than "Ummm Ummm Good!!!"  I tried this for the first time at a BBQ on a salmon burger and it truly brought the flavor out of the meat...now I use it on everything from chicken burgers to homemade Caesers dressing!  You'll love it!!!
