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: This is my fourth order of these pork rinds and I'm not sure what's up, but something's really amiss. The bags are leaking some kind of grease and don't fluff up during the microwave process. I used to love these, so hopefully this is just a bad batch. If not, then Lowrey's needs to look into this and fix whatever has happened to a once great snack.
Example Output: 1

Example Input: Ordered on a whim. My first "Grove Square" purchase. Great for the family's occasional cocoa desire. Being a K-Cup it's fast and easy. Was a little worried the cocoa might leave some after taste in my coffee, so far so good. Great cup of dark, rich cocoa. Maybe could taste a LITTLE better if it was from a gourmet brand you mix yourself with steamed milk. The ease and simplicity, and lack of clean up, make this a better option for me. Will order again. Nice to see it on subscribe and save.
Example Output: 5

Example Input: I've sampled several varieties of Eden Organic beans; this is the only one which i found to taste truly awful. Of course taste is subjective, so your mileage may vary. My advice, before committing to a case purchase, is to first sample this variety by buying a single can from a local store. If that's not an option for you, then you might consider moving on to another variety. I can recommend their black, pinto, and great northern beans. If you're looking for something out of the ordinary, you might consider their <a href="http://www.amazon.com/gp/product/B000HDMUOE">Aduki Beans</a>. I like the fact that all Eden Organic beans are in BPA free cans. Too bad that not all their canned products are BPA free (e.g. as of this writing, Eden canned tomatoes, soups, etc. have BPA linings).
