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 Melitta Riviera Sunset blend is a nice, and light coffee that is suitable for anytime of day. It's particularly great for drinking at night because it is decaffeinated. The texture is nice, and does not have an acidic taste or anything. It's meant for casual drinkers. I do prefer my coffee darker, WITH caffine, but I did enjoy this blend. I would recommend giving this a try and judge for yourself.
Example Output: 4

Example Input: Nothing but good feedback from everyone. A very good classic tasting licorice product. We buy it on subscription and save shipping and a little money.
Example Output: 5

Example Input: I would agree with the other poor ratings for Royal Oak - very poor customer service from Royal Oak. We ordered, this year, the exact same product as last year. When it arrived, the nuts were not the same product, and they would not refund or pay shipping for the return. Also, they only operate the few weeks that peanuts are 'in season.' Otherwise, emails and phone calls are not even acknowledged.
Example Output:
