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 was out to dinner with friends & family at "The Saloon" in "Rte 46 Entertainment Complex" in Sanford FL. Besides having an awesome staff (ask for Keith) and fabulous food (the escargot is a MUST) they serve China Mist tea. This is the 1st time I chose the Tropical Organic Green -- I have no doubt it is the best flavored tea I have ever had.
Example Output:
