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 has a strong after-taste of Crayola crayons! I am in the process of trying different brands of coconut oils for cooking purposes. Upon opening the plastic container, the aroma of crayons immediately fills the room, and this flavor permeates the food that is cooked in it. I suspect the source of the problem is the plastic used in the plastic container as I have not experienced this with any of the other brands purchased. To date, my favorite coconut oil is distributed by Barleans. The flavor is fantastic. However, they do not supply a gallon-sized tub,and Dr. Mercola has the best product in that size category.

Example Input: This hot chocolate tastes like hot sugar water with a pinch of coco in it. Although, even the sugary taste is weak, and tainted by the flavor of the artificial sweetener sucralose. The consistency is watery and bland. This is when I made the 8oz cup as directed by the directions on the box. I do not recommend this product.

Example Input: Thought these were the larger sized ones you see in stores but I was mistaken. These pops are about 7" inches long and a little less than 1" inch wide. Flavors are comparable to Flavor-Ice, not necessarily better. My wife and I enjoy these throughout the year instead of ice cream, but we can only find them in our local grocery store during the summer months. Glad we can get them via Amazon! These were on sale for $5.48 per box of 100 with free shipping, so I think we got a good value. Without the sale pricing, I'm not sure if we'd choose these over another brand, but if they do go on sale again, we would probably buy them again. Not bad, just a little small... Eat two! ;-)
