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: Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.
Example Output: 5

Example Input: We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.
Example Output: 5

Example Input: I was familiar with a few of Wolfgang's recipes before I tried any of his soups. First I tried a different flavor a year ago, but can't remember anything except it being bland and slimy.  I decided to try it a 30 minutes ago because I was desperate for something healthy and convenient because I was a tad sick and could not make my own unprocessed meal with the ingredients I had home. I bought it for about $3 and hoped I just had a bad can of soup the first time, but this was just awful. No taste, slimy, and hardly any chicken (probably 3-4 tiny pieces). I can see why they added such little chicken. It's just tasteless and dry; tasted nothing like chicken. I'll go try another can of soup that can make me feel a bit better. This sure didn't do it. I have never had soup that tasted bland even after adding salt and seasoning. I see positive reviews that make me thing I had another bad can because I still can't believe it had absolutely no flavor.
