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: It may be all natural but it didn't have a natural taste to me. The can size is small and the calories were more than I thought there should be. I like the mild carbonation ok but I wouldn't switch from orange juice.
Example Output: 3

Example Input: The Melitta Java Pods Have a slightly smaller circumference than the Senseo pods and are thicker. If you are using a Senseo coffee machine, you probably should moisten the Java pod and smooth it before attempting to latch the lid. Otherwise, you risk breaking the latching mechanism. The resulting decaf coffee is not bad and seems to this reviewer to have a richer taste than the Senseo decaf pods. The Melitta Java pods are not really designed for the Senseo machine and several other brands such as Halo, Fratello and Millstone work better in the Senseo machine.
Example Output: 3

Example Input: I do a lot of "from scratch" gluten free cooking but there is nothing that can replace Bisquick. From the ease of morning pancakes to using it in other reciepes in place of other mixes there is simply nothing that I cannot do with this little box.
Example Output:
