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: Delivered by UPS, this product is just about perfect. It does not have a disagreeable smell and the dogs love it. It is much less expensive than prescription dogfood and our dogs are thriving on it. You can even see an occasional pea and/or carrot. No grain to worry about.
Example Output: 5

Example Input: I was on subscribe and save for these mints, but have switched to Spry due to Xylitol USA's awful company policy and customer service. If you buy something from Xylitol USA that arrives in bad shape and you want to return it for a refund, the company will tell you that they do not accept food back. When I insisted that the product was old (in my case two bags of xylitol sweetened dark chocolates that were old, whitish and tasteless) they said that they would NOT refund my money and, amazingly enough, offered a 25% discount on my NEXT purchase. I disputed the payment and my bank took care of the situation got me my money back. No more purchases from this company for me.
Example Output: 2

Example Input: Well, maybe I'm the first one to review this wonderful treat, but I know I'm not the first one having tried them! This treat is so safe, healthy, and yummy! In my native language, Miam-Miam is for Yum-Yum! There you go. Not too sweet, yet not lacking sweetness. You can't taste one ingredient above the other one (OK, besides the coconut, since it's mostly made of it), it's so good. This is a raw food product that has been dehydrated at low temps, it's really nice to give to our kids. (We have 7 of them, and they love it). Of course it's a bit more expensive than your average treats/candies, but hey, who wants to complain? Do you want crappy candies with dyes, chemicals and cooked (so basically poison), or you want to give REAL FOOD for yourself and your kids? I bet if people learn to do/prepare these treats and give that to their kids, school would be less filled with Asperger Syndromes, ADD, ADHD kids etc.... This is a treat that you won't regret having spent money on it, unless of course... you are so used to the chemical loaded-pesticide-herbicide-overly cooked-High Fructose Corn Syrup-dyed candy, then it's not for you. Keep your money instead, you'll need it for the bills you'll have when you go to the numerous Docs that can't help you and your kids. Sorry....:(
