Given the task definition, example input & output, solve the new input case.
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: 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.
Output: 5
The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

New input case for you: I bought these bars for several years at my local co-operative grocery store, and ate them daily--they are tasty. However, the price increased nearly 100% during that time, and I noticed that, although the individual wrappers within the box remained the same size, the bar within the wrapper decreased. When I stopped buying these, the actual bar was only half the size of the wrapper. That's deceptive packaging, so I refuse to buy these any more. I suspect that other shoppers likewise complained, because last month the store where I bought these stopped carrying them.
