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 admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.
Example Output: 5

Example Input: My son loved all the sauces.  The only sauce that was way too hot was the Insanity Sauce, use a teensy tiny bit when using.
Example Output: 4
