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 product and the Urbani white Truffle oil and it arrived broken because they shipped it in a box with nothing inside to protect it. It was just 4 glass bottles thrown into a box and shipped. Also there were no markings on the box to say it was fragile or that there was glass inside.  When I tried to go online and return it I was told the items were not returnable.  So I just bought some expensive, broken, oil.  I will not5 buy from this again and would advise everyone else to do the same.
Example Output: 1

Example Input: This is a great product.  We tried it at the beach the first time and loved it.  The cashew crunch was not as good. We bought a case of the almond this week.  Just great!
Example Output: 5

Example Input: LOVE this!  I dislike drinking plain water and have been looking for something easy that I could add to my s/s water bottle (gotta be good to the environment, right?)  The flavor is great, ease of convenience is wonderful and the hint of sweet is not overpowering at all.  I can drink my green tea with or without sweetener.  The only thing is if you want to drink green tea all day long, the calories WILL add up - I think each packet is 60 calories.  I drink 2 (32 oz) bottles of water a day so that would be 120 calories of sweetened drink a day.  But I will still give the product 5 stars because the product is fab.  I'd just pick something else if I'm going to pound water all day long (perhaps the blueberry green tea one which is NOT sweetened - it's excellent as well)  I'll use this for one bottle and a non-sweetened one for the other.  Best of both worlds.  Enjoy!
