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 a confession to make:  I had one of these bars and a cup of coffee for breakfast, and it was actually not bad.  But the Amazon stars say "I love it" for 5 stars, "I like it" for 4 stars and "It's okay" for 3 stars.  So, I give it 3 stars.  I personally felt the coconut flavor was stronger than the chocolate flavor and I'm not a big coconut fan, but I am a chocolate fan.  It wasn't terribly sweet and I rather think I would have liked it a little better if it had been sweeter (but not too sweet - I'm kind of picky that way).  I liked the oats and the "gluten free"-ness of it.  I don't eat gluten, so that makes bread/bagels pretty expensive.  These worked out best for breakfast, although I think I used it as a going to bed snack a couple of times.  So, just for fun, I got some nutritional information from 1) Pamela's Oat Chocolate Chip bars 2) some unsalted, dry roasted peanuts and 3) some non-gluten gingersnaps.  1) 1, 1.41 oz bar  -had 9g fat, 15 mg cholesterol, 130 mg sodium and 2g of protein. 2) 1 oz (40 nuts)  -had 14g fat, 0mg cholesterol, 0mg sodium and 7g protein. 3) 5 cookies (30g or 1.06 oz)  -had 6g fat, 0mg cholesterol, 85 mg sodium and 2g protein.  I think that each of these snacks might serve at one point or another.  If you are looking for high protein, then neither the cookies or the Pamela's bars would do the trick, confirming that the Pamela's bars would be more of a snack than a meal.  So don't eat one of these with coffee for breakfast.  Ever.

Example Input: Fiber one products actually don't have real fiber.  They contain inulin (from chicory root) which is technically fiber because the body can't digest it.  Unfortunately fiber is defined by anything that can't be broken down easily.  These products do not contain REAL fiber. (The real fiber usually found in whole grain breads and bran cereals) So if it says "chicory root" or "inulin" in the ingredients, you can be sure you aren't eating the fiber your body can actually use.  So if you want lots of sugar and fat without fiber, this product is for you.

Example Input: Actually saves my basil and cilantro for an extra week or two. Thats enough reason for me to buy! Before my basil and cilantro would last only a couple days and I would have to toss them out. This saves me money and a trip to the market!
