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 was amazed at how good this is for canned fruit (which I normally won't touch).  In particular I adore papayas and mangos.  The fruit juice instead of syrup is also very nice.  The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch.  So far I haven't gotten a can that had any problems.  The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".
Example Output: 5

Example Input: I love the flavor that this hot chocolate has.  It is very rich and smooth.  Have tried other brands but did not get the results I wanted.  I will definately be ordering from this company again.
Example Output: 5

Example Input: I've been eating the McDougall Right Foods for a few years now, and this is by far the best.  It takes exactly the way the name suggests.  It tastes great with cooked vegetables such as broccoli and cauliflower, and it is very easy to make.  The only problem I have with it is that the noodles aren't thick enough for me, but I think one time I let them sit in the microwave a little longer and they became thick.  Other than that, I'd recommend this product to anyone who wants to eat healthy and who enjoys noodles and peanut flavor.
