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: Short and sweet.....The product itself is top notch and my two GSD's love it. However, the last shipment looked like it was packaged by a three year old and thus it arrived via UPS with a can lid popped open spilling its contents over the other dented cans. Another case arrived seperately which was properly packaged using air pillows and was fine. Don't get sloppy Amazon. It will cost you customers.
Example Output: 3

Example Input: Folks who are comparing this to Hodgson's blueberry muffin mix obviously don't require gluten-free products (since the blueberry are whole wheat muffins). If, like me, you require gluten free, this is a great product. This is the first flavorful GF baked good I have stumbled upon. Very simple and quick to make. Like all GF products, they are pretty dense in the end, but the apples make for a nice addition and they fill you up. Personally, I added a bit more "sugar" (xylitol) than the recipe calls for. Next batch, I will also add some fresh apples and extra cinnamon. My only complaint is that you get so little out of the box (makes 6 small muffins).
Example Output: 4

Example Input: This tea has surpassed all other breakfast teas in this tea-drinking household. We love it and it really starts the morning off right. Perhaps it has more caffeine than our old favorites?? The taste is wonderful without any additions and it will remain our tea of choice in the morning and often throughout the day.
