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 product is good. However, I feel the carbonation is a little more emphasised over the fruity flavor. Unless of course carbonation is really wanted. I didn't find the juice flavour as good as Juicy Juice. And the cost is ~50% more per ounce for Switch vs. Juicy Juice for my region.  I would say that for everyone who is interested in this product... let your taste buds be your guide.
Example Output: 3

Example Input: The taste is great but most of the crackers are broken.  I am maybe getting 12 whole crackers per box.  The first time I ordered these there were several broken but this time there are more broken than whole.
Example Output: 3

Example Input: It is not a bad drink. It tastes great but nothing like Kiwi Berry flavor. I can taste more of the apple or punch flavor. I like that it is all natural with no preservatives but I did not like the fact that it is very carbonated. I also like the fact that it does not have corn syrup or sugar that is in most other carbonated beverages.
Example Output:
