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 was happily surprised with this product. I read other negative reviews and was honestly disappointed in Betty Crocker gf cake mix so I didn't feel the need to try this. I finally bought it at a whim when I saw it at my local market and I am happy I did. I am a baker at heart and love to spoil my family with homemade deserts and pancakes on the weekends. I have adjusted my cooking and baking to primarily gf for the past year now and am happy when I find a gf alternative that cooks & tastes like "the real thing". Another plus is that I can buy this at my local market (which does not carry too many specialty foods) and don't have to make the extra trip to the higher end store. I made pancakes today and they were a hit with everyone. Will definitely use it to try other recipes. Only downside is the cost and size of box; very pricey and very small.
Example Output: 5

Example Input: I have this on auto ship because I use it so much. I have gone to every grocery in AZ and the cheapest place is Amazon! This is a great product and whatever you make using this flour will taste great. My son has Celiac and is allergic to gluten. I have tried every pancake mix and this one is the one I settled for!
Example Output: 5

Example Input: The title says it. Some of the cookies arrived with the chocolate melted. Others were stuck together or had the wafer separated and stuck to the chocolate top of the cookie below. It appears that the box was a little overheated and banged around somewhere along the way here. It was 65F here when the package was delivered.
