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've used this BBQ sauce before and it is good especially considering that is free of so many negatives (like corn syrup and for us gluten) but the price on this can't be right.  Order directly from the Daddy Sam's website to pay $5.50/19 oz bottle.  This price would HAVE to be a case price although the description says 19oz.
Example Output: 4

Example Input: In all fairness my friend absolutely loves this product.  I purchased it based upon his suggestion.  Unfortunately, the smell (oil I am assuming) of it cooking made me feel ill.  Even though the product cooked perfectly, the smell lingered in my microwave for well over a day.
Example Output: 2

Example Input: This flavor is awful! We absolutely love all the other flavors but goji cacao & maca is really difficult to get down. I give all the other flavors 5 stars!
