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 like the dried peas from Just tomatoes and I also like their Just Corn.  They are way too expensive though.  They are really handy because I don't use frozen or canned foods because I follow an Ayurvedic diet which prohibits them.  When I can not find fresh peas I have to use these.  I will probably have to do without as I can't afford these, too bad.
Example Output: 3

Example Input: There should be an option for a 0 star rating because that is what I would rate this item. First, the sampling was to include 9 varieties but included only 7.  It appears that the two flavors out of stock were not substituted with two other flavors but instead a few more of the remaining flavors were tossed in the box. I had expected that when a limited edition coffee flavor such as Island Coconut was out of stock, it would be replaced with a different limited edition coffee flavor.  Same thing for the Half and Half Lemonade. Second, the order was not balanced.  Of the 7 flavors I did receive, only 2 were coffees, the remaining 5 were teas. The concept of a summer sampler set is a good one but the execution here was an epic fail.  The order is being returned today.
Example Output: 1

Example Input: My kids love brownies, but I could no longer by the regular brands in the grocery store with a good conscious.  I still wanted the convenience of a mix, though.  These fit the bill.  They first time I made them, they thought they tasted "funny" because they were so used to the processed crap.  Now they eat them up and have gotten used to the flax taste.  I think they are YUMMY! These are in no way low-calorie or low-fat though.  Instructions call for a lot of oil, eggs, and butter (you can use Earth Balance and egg replacer if you're vegan).  Flax seeds also have a good amount of fat (although the healthy kind). I've made them with olive oil before and they were just as good.  I've also added extra organic cocoa powder to make them extra chocolatey, but they really don't need it.  I love the chewy texture of the flax seeds.  There are very few ingredients, I could probably make the same brownies homemade, but it would be a pain to have to grind the flax seeds, etc.  These are easy and yummy.  Even though they are not necessarily "healthy" from a calorie and fat standpoint, I can feel good about giving my kids treats that aren't loaded with processed crap.
