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: It wasn't a bad purchase at just $9.99 through Warehouse Deals fulfilled by Amazon and shipped for free, but took 2 stars off because it wasn't a freshness issue but Cracker Jacks® just don't taste the same like when I was a kid back in the 1980's.
Example Output: 3

Example Input: These are super tastey! I would definitely recommend. The only reason I'm not giving 5 stars is because I wish they were bigger! :D
Example Output: 4

Example Input: I have 2 husky/shepherd mixes. The first is 13 months and has a finicky stomach - if he eats too fast, drinks too fast, or eats anything out of his routine, he would bring it back up. He also wouldn't eat more than a few nibbles at a time. The 2nd is 7 months old and came to us with severe diarrhea (vet's food didn't fix it either). He would eat anything and everything if we let him. Within a day of both dogs being on Harmony Farms (No fasting, just a quick switch), both dogs digestive issues are gone. My oldest (the finicky eater) is healthily eating his meals without pause or hesitation. My youngest has solid, regular bathroom breaks and has been able to relax his water intake as a result. They're both more relaxed. We purchase at our local grocery store (Hannaford here in NY) for about $1.31/lb. For the price, ingredients, and results - you can't beat it.
