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: This is my fourth order of these pork rinds and I'm not sure what's up, but something's really amiss.  The bags are leaking some kind of grease and don't fluff up during the microwave process.  I used to love these, so hopefully this is just a bad batch.  If not, then Lowrey's needs to look into this and fix whatever has happened to a once great snack.
Example Output: 1

Example Input: I have been making Belgian waffles using the Stonewall Kitchen Farmhouse Pancake and Waffle Mix for over three years.  My waffles are undoubtedly the best ever!!!  I like my waffles light and crisp - I can't stand a heavy soggy waffle. These just melt in your mouth.  I have made homemade waffles, but I have yet to find anything that can compare to this mix.
Example Output: 5

Example Input: Chewy Lemonhead and Friends are my favorite candy. Period. I love them...so much. ...(cough) So when I found these I was really excited and bought a pack hoping they'd have that same tartness that makes Lemonhead and Friends so good! Nope. Tasted just like every other jelly-gummy type candy. I was very let down. It was okay for jelly/gummy, but don't expect much.
