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: Why in the world would Amazon want to sell an item and say can be ingested, when it clearly has ingredients that can cause cancer. Wish every state would wake up like California and ban all these cancer causing things.
Example Output: 2

Example Input: Different flavors for different people. Not everyone is going to like this just as others, like me, will love this coffee. It's totally subjective. I give it 5 stars. I enjoy this coffee a lot and the price is very reasonable, in my opinion. It matches my local big box grocery store.
Example Output: 5

Example Input: I tried this as an alternative to Kashi's Honey Almond Flax (Chewy Granola) bars, which I love almost as much as the Roasted Almond Crunch (Crunchy Granola) bars. It's possible I'd like the Tail Mix bars when I'm in the middle of a long, strenuous hike, but it could be months before I test that hypothesis. Simply put, I don't have much of a sweet tooth, and these are overly sweet for me as a mid-afternoon snack at the office. However, after trying this and that without much satisfaction, I've found a solution that will help me get through all these bars rather than having to ship them back. I bought some Uncrystallized Candied Ginger at Trader Joe's, and the heat of the ginger--plus a few almonds--is a perfect foil. (For those of you wondering, the sweetness is from dried cranberries and raisins.)
