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: 10 out of 12 cans are seriously dented , and, the dents did not occur during shipping. These were dented befor they were packed in the case of 12 at the factory. These will get trashed because it will be more of a pain to return them. I will never buy these again !!! Amazon did refund my money without having me return the cans. Cudos to Amazon. They are a class act!
Example Output: 1

Example Input: This stuff tastes great! I am not a decaf person, but perhaps I am being won over by Melitta coffee - try it!
