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 ordered this because so many people were saying that it was sugar free. It's not. The first ingredient is "SUGAR". It's too much of a pain to return, so I'll keep it and drink it (because it's a pretty good K-cup hot chocolate). I will think twice about ordering it again though. I'd really like to get what I ordered.
Example Output: 4

Example Input: there is a taste of sugar substitute, the aftertaste turns me off, I've even tried using a little bit of milk in the mug before hand to hide the taste. It didn't, so i'm just using Swiss miss powder and a little milk to make it a creamier hot chocolate before using using my keurig.
Example Output: 2

Example Input: This food is great. My 11 year old beagle loves it and she is much more active since I changed her food. I highly recommend this dog food.
