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 been looking at this product for a couple months and finally gave in.  First of all, the name got my interest!  The taste is delicious BUT I'm having problems with the directions!  Haven't figured out if it's actually a hot beverage or do you put it in a hot beverage?!?!?!?!?  It has a scoop (small) and says to put that in a cup (instructions for 8 oz.) and then put a couple "shots" of hot water!  Shots of water????  And you can add frothing milk.  Hum!  Confused but I guess I will work with it.  Hope it doesn't take the whole container (very large) to figure it out. I would have given it 5 stars had I understood the instructions!
Example Output: 4

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: For all of you potato chips lovers who are trying to eat healthy, these chips are a great alternative!  No they are not like fried, but the flavor along with the calorie/fat benefits make this a great choice! I liked having the variety pack for the opportunity to see which flavors I would like. As it turns out, I like them all! But I do have my favorites (like BBQ, salt & vinegar, and plain) so being able to buy them singlularly is an added plus.  I have already placed two orders since my initial purchase!
