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 really liked this flavor! As someone with many food sensitivities who also avoids sugar, this is the perfect treat for me when I crave chocolate or baked goods. The raw nuts are crisp and fresh tasting. However, the price was very high for the quantity of product. With less than 20 brazil nuts in the package, I felt a little gipped. In future, I'll try making my own chocolate nut mix from bulk raw nuts, berries, and coco powder rather than spend $9 per package! For that price, I'd like a lot more product.
Example Output: 3

Example Input: I am a fan of Silver Palate cookbooks and was delighted to see this sauce on the grocery shelf. After getting it home and warming it in a saucepan, I gave it a taste. It was so salty, it was inedible. (And I am not reluctant to use salt.) 660 mg of sodium per 1/2 cup? Are they serious? The salt overpowers any subtle flavors in the sauce. With hypertension representing a major health problem, this is irresponsible. It leaves a bad taste in more ways than one.
Example Output: 1

Example Input: Was awful. The sight of this in my pan made me sick...smells like POTATO duh potato starch)...would not brown. My child laughed the entire time...as I complained because I was so hungry and thought I could have a late night pancake session. Totally not the case. Yes, I am a GF newbie... I tossed the box!
