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, the good news:  YES, these are really good. the bad news: They are loaded with monosodium glutamate Of course, this wasn't listed on Amazon as one of the ingredients. This is a good item if you're not sensitive to MSG-- Now I have to go to the 7-11 and buy the fried pork rinds to feed my addiction.
Example Output: 1

Example Input: I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.
Example Output: 4

Example Input: I always disliked soggy or soft crackers with my peanut butter.  And since I also had discovered I was allergic to wheat, I wanted and needed an alternative.  I originally found these Kame Rice Crunch crackers in Kroger supermarkets.  From the first bite, I loved them, and I wished I had discovered them years ago.  The plain variety has just the right amount of salt for taste, and they are perfectly crunchy and light.  I've occasionally had a hard time finding them, so I'm THRILLED that Amazon is now carrying them.  Give these a try, they are delicious!!
