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'm a little shocked that this so-called health food product is made from Chinese grown ingredients.  I'd be curious to see what the carbon footprint of each bite is.  Also keep in mind that Chinese ingredients and products have been found to have all kinds of contaminants such as lead in toys and melamine in milk and other exported food products. All the ingredients in this snack are widely available in the United States.  Why not support products and companies who source locally and consider our own economy before we sell out for a slightly cheaper price?  Your purchasing choice does make a difference.  Let's stop expecting corporations and governments to take care of our safety and economy.  They never will.  We can change the way these companies do business for the benefit of our long term health and economical well-being. Make purchase decisions wisely.
Example Output: 1

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: If you like the flavor of green tea and like your beverage iced you will enjoy this beverage.  I like the taste of green tea and I also like the health benefits of green tea.  I mix this with ice water and splenda.  It is a refreshing summer beverage.  I like that it dissolves easily and is packaged in small packages.  It is convenient and easy to use.
