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 get around a shipment a week all year round from Amazon, and I can not remember ever writing a review. But I am making a point of expressing my anger over this product. I buy lots of tea from many sources and white peony is one of my favorites. The package says it is organic and of the finest quality. It was possibly the worst tea I have ever tasted. In fact, after a couple of pots, I actually threw nearly the whole half pound in the trash. And the price wasn't even that good. I subsequently bought a pound of excellent organic white peony from Whole Foods for less. Whatever they are, this is not a tea company.

Example Input: These are the worst gluten free cookies I have ever tasted.  They were hard, dry and tasted like tapioca flour.  Avoid these at all cost.

Example Input: This product claims to be a healthy carbonated product. This particular flavor is very heavy on the orange taste (which is to be expected). As a matter of fact, I found it very close to normal orange soda.  Here are the claims of the product from the label:  100% juice, 100% RDA Vitamin C, All Natural, Carbonated, Great Taste and Refreshment.  No Sugar Added, No Corn Syrup, No Preservatives, No Artificial Colors, Gluten Free  Nutritional Information:  Serving Size 8.3 Fl. Oz. (245 ml) Servings: 1  Calories: 140 Fat: 0g Sodium: 15 mg Total Carb: 36g (Sugar 34g) Protein: 0g  Vitamin C: 100% RDA Vitamin A: 20%  Ingredients:  100% Juice (filtered spring water sufficient to reconstitute concentrates, apple grape, tangerine, orange and acerola juice concentrates), gum acacia, natural flavors and colors, ascorbic acid (vitamin C). Contains Soy.  Compared to soda, it is healthier in that it doesn't contain added sugars or corn syrup.  But it still has a bunch of calories.  Eating fruits whole is better than juice, but if you want a quick soda-like pick me up (and you love orange soda), I would recommend this product over regular soda.  I gave this product 3 stars because I don't think it really is that healthy, but is a decent alternative to regular soda. Also, the taste was ok, nothing remarkable.
