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: First off,  let me state that I am not a fan of decaffeinated coffee of any type.  But I often have guests over who ask for de-caf, so I gave this a try.  While I agree with some other reviewers who have stated that there is a certain "different" taste about this blend, for me, it was not a bitter taste, but instead, a good, strong flavor that mimicked the strong (real) coffee taste I enjoy.  I had a second cup, and the flavor grew on me even more, and I thought: "it really is delicious for a decaf."  The aroma isn't truly satisfying (why does this always happen with decaf?) but I think many decaf drinkers will be used to that lack.  The package had to be snipped open with scissors --this is tightly packed!-- and then I just poured it into a zip loc for storage in the fridge.  I'll stick with regular coffee, but I'm sure my de-caf loving friends will enjoy this.
Example Output: 4

Example Input: As another reviewer mentioned, these treats are CRUNCHY!. I like them for 2 reasons..my dog can't just "woof them down", she has to chew them, so they last..and I like that the cruchiness may be good for her teeth. The treats are small, but again, are crunchy...I'm glad I found these. She loves them and I like giving them to her.

Example Input: When I saw the Switch Orange Tangerine was available, I knew I had to try it.  I liked the Kiwi Strawberry quite well (better than some other reviewers did, it seems), so I was sure I would enjoy this one just as much.  The initial taste of this Orange Tangerine carbonated juice is rather tart, and the carbonation just seems to make it more tart.  The aftertaste is rather pleasant, so if the aftertaste is what you're looking for in a drink, this is the drink for you.  My wife thought it tasted a bit like champagne, if that's any indication of what to expect from this drink.  The flavor is different, and not at all what I expected.  Not very refreshing at all.  I would buy the Kiwi Berry drink, but I think I'll take a pass on the Orange Tangerine in the future.
