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 ordered this product - Lowry's Pork Rind - and received it promptly - within two days.  I have not been able to pop one bag!  They all stay flat - nothing works.  My microwave is not the problem as I cook lots of other things in it.  Looks to me that the product is not longer any good, by the comments.  They may have started out great, but it NO LONGER IS WORTH BUYING!
Example Output: 1

Example Input: I have managed to find these crackers in other countries on our travels but had run out. I love that they are individually wrapped small packets in a stay fresh container. This makes them great to carry in my purse, take to work or on airplanes for snacks etc. Also love that they are not overly salted like so many American brand crackers. Company that shipped them did a great job - fast too!
Example Output: 5

Example Input: Licorice Jelly Beans use to be my absolute favorite in the jelly bean flavors (I no longer eat sugar).  These were bought as a gift, so I did get to try a few just to see how they  are.  I've had many over the years before giving up on sugar and honestly have never had any with this good a flavor!  Also their customer service is excellent! I needed to contact them and they were very responsive and also willing to do just about anything to make sure even ONE customer is happy - something lacking in most companies these days. To compare - I tried a couple Jelly Belly licorice ones and to me they had a fruit flavor that was just wrong - not enough of a licorice taste.  Gimbal's is less expensive this way and superior in every aspect of a licorice jelly bean.  This is a LARGE quantity!! Keep that in mind when purchasing - either have a lot of jelly bean lovers in your life, or a large family or collection of friends to share with - unless of course your sweet tooth won't stop and then, just savor them all yourself ;-) Enjoy!
