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: It's a refreshing drink when served cold. A bit sweet when warm. A little tart, but tolerably so.  The flavor is less orange than tangerine, yet I can distinguish several different "layers" of citrus in it, including the orange. It's an interesting sensation.  I am a little bugged by the fact that an 8.3oz can (2/3rd-size) manages to pack more junk calories in than a full-sized can of cola. It's also supposed to be 100% juice, but reconstituted grape juice is practically pure sugar and there are "natural flavors" noted in the ingredients list as well as a soy warning which to me implies some sort of MSG, probably added with the citric acid.  So, maybe it's not an especially healthy beverage. It's still tasty and provides a diversion from more typical sodas.

Example Input: I've read lots of other reviews deeming this tea as "coffee tasting" or with "roasted flavors," but to be very truthful, it tastes just the way I could imagine second hand smoke would. It's very very strong, requires 15 minutes to steep, and is not for the faint hearted. I've heard wonderful reviews related to weight loss regarding this product, but I was not able to tolerate the taste long enough to actually see any weight loss benefits. Good luck to those who care to brave this "roasted" flavor.
