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: The cookies came sealed and seem to be high quality in there ingredients.  The only thing is they just don't taste that good. My girlfriend and I thought these might be a good dessert-like option while doing the Paleo diet, but after trying one of each kind over a couple days we just don't find ourselves going back for more.  I would much rather not have a dessert and really check that box on a cheat day than being left wanting more after eating these.  If you have a true gluten allergy, maybe this is a good option for you but I'm not a believer.
Example Output: 3

Example Input: I enjoy them a lot and so does my son. I have to say that this kind is one of my favorites. It is full of peanut butter flavor that you forget that it is only 100 cals. As for the amount you get in the bag, it is more than I expecting so I was very happy.
Example Output: 5

Example Input: I really love the oatmeal raisin cookies I ordered from Pamela's, but these were really bad - they were dry, tasteless and seemed old.  Going back to Pamela's oatmeal raisin - if I can find them.
