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 have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Example output: 5
Example explanation: The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.
Q: I tried this gum after Trident cinnamon became hard to find a couple of years ago. (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.) I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back. It does last a long, long, long, time. Unfortunatley, as other reviewers noted, it has become very hard to find in stores. Trident cinnamon is everywhere but now I don't want it. Amazon saves the day again.
