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 have a recurring shipment of this product each month.  Every month when the boxes arrive they are barely in one piece and VERY mangled.  Last month one of the cases of water had to be repackaged before it arrived and it was a day late.  I suggest using a more sturdy box for shipping.  The water product is fine ... it's just the shipping packaging I have a problem with.
Example Output: 2

Example Input: Work well and made solidly.  For whatever reason the Keurig takes longer to complete the brewing cycle when using these cups and the liquid bleeds through the filter on the outside of the cup making a small mess.  They do the job as intended but could use a different type of filter to make the experience less messy.
Example Output: 3

Example Input: Let me be honest, I wasn't expecting this to be very good. I received a sample and it sat in the fridge for a good week before I was brave enough to give it a taste.  At first sip, it was much sweeter than I expected it to be. I could certainly taste the pineapple, but the coconut flavor was much more pronounced than I thought it would be. It was good! I very much enjoyed the taste of the drink. It was exotic and refreshing. It was much fuller in weight, as I was thinking it would be watery with a mild flavor.  The box reminded me of those chocolate milks that I buy for my kids, but it didn't detract from the flavor.
