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: I got this drink expecting the carbonated taste combined with kiwi and berries. Well I could taste the berries but no kiwi. I did like the carbonation with real fruit juices without the added sugar but it is not low cal. I think that I liked this drink better than the tangerine drink but still is not for me. The drink is way too sweet for me to enjoy it.

Example Input: I have bought many brands on peanuts on Amazon. I was a tad disappointed in this brand. The Peanut Shop Of Williamsburg. The over all flavor was ok. Not a strong flavor but not weak. I found the salting to be a little on the light side. That's fine with me, I use most of my nuts in kung-pow type dishes, and the lower salt is fine. The crispness was very poor for a hand cooked kettle peanut. It really should have more crunch/snap.  Over all this is a step up from Planters cocktail peanuts. But you can do much better with other brands.
