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 just received these bricks today and was very disappointed to find that BOTH of the bricks were broken and unusable as a serving/cooking plate.  They were busted completed in half. They were packaged in one sleeve of small bubble wrap in a shallow box with no other protection or packaging in the box.  I went online to try and return them and they are not eligible for return.  This is the first return I've ever tried to do in over 7 years of purchasing items off of amazon (to the tune of several orders a month!) and yet the one time that I want to return a defective product, I can't do it.  I will be much more careful about what is eligible for returns and what isn't in the future.
Example Output: 1

Example Input: Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level.  Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.
Example Output: 2

Example Input: THis ice tea, is like heaven on ice.  must try if you love lemon and giger.  Great price for the content.  You can make a pitcher with 4 bags and add some lemon and whatever your sweetner you prefer.  Great for barbeque parties or a tea with the ladies
