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: I really liked this flavor!  As someone with many food sensitivities who also avoids sugar, this is the perfect treat for me when I crave chocolate or baked goods.  The raw nuts are crisp and fresh tasting.  However, the price was very high for the quantity of product.  With less than 20 brazil nuts in the package, I felt a little gipped.  In future, I'll try making my own chocolate nut mix from bulk raw nuts, berries, and coco powder rather than spend $9 per package!  For that price, I'd like a lot more product.
Example Output: 3

Example Input: Well the creme caramel was on sale so I decided to give it a shot. Plus the fact that each K Cup is individually prepared by Mr. Puck himself. Anyway I quite enjoy these. I never buy flavored ones so overall I'm happy with these but they are definitely not my favorite as I usually buy the bolder ones and these are fairly mild.
