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: Delivery of the product was quick, however the items are smaller than how they appear on line. Next time I would order the larger size.
Example Output: 3

Example Input: This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)
Example Output: 3

Example Input: Delicious cookies.  I actually thought I was ordering the white chocolate chunk cookies, not the chewy, but definitely enjoyed these.  The only down side, is these seem awfully small.
Example Output:
