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: For starters, I'm not salt or msg averse. I enjoy salty food like chips, jerky, and bacon. However, these pork rinds are ridiculously salty tasting. To give you a better idea of what I'm referring to, Kettle Chips Sea Salt variety have 55 mg of salt per 1/2 oz of chips. Lowrey's pork rinds have 310 mg of sodium per 1/2 oz serving. That's roughly six times the salt content of a food considered relatively salty by most people. I read a review on here saying that they were too salty and decided to order them anyway thinking the reviewer was some salt hating baby. Boy, was I mistaken. I wish I hadn't ordered these.
Example Output: 1

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: I'm sitting here, (Switch) drink in hand, trying to decide how to describe the Switch Kiwi Berry. It's lightly carbonated, which I like but too sweet for my taste (think strawberry candy). The mouth feel is quite round and it has some body too it. It's made from juice concentrates and carbonated water and there are 135 calories of sugar in the small 8 oz can. I wouldn't call it a healthy beverage and whether it's natural or not doesn't matter to me.
