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 a close second to my all-time favorite, Jack Links Beef Steakhouse Steaks, which is the filet mignon of beef jerky. They're very similar in taste and price, but the Steakhouse edges out this one oh so slightly. Still pretty awesome jerky, very tender, and not a hint of fat or gristle. Bon appetit!

Example Input: These pods are so much better than the Senseo pods!  At 10 grams, these pods are packed with more coffee than the Senseo pods, making for a better, stronger, more flavorful cup of coffee.  I use these in my Melitta One-One.  Also love that each pod is individually packaged, so they stay fresh.  They come in a stand-up box dispenser which is nice too.  I can't understand the other reviewer here who didn't like the coffee - I love this decaf!  It really is the best pod I've found.  Also the value here can't be beat.  Comes 3 boxes in each order, so in each order you get 54 pods!  And Baronet has so many flavors.  Do check on the other Baronet flavors, though, because all the Baronet pods are not 10 grams, and all the pods don't come individually packaged.  Stick to the 10 gram, individually packaged pods, you won't be disappointed.  I get three different Baronet coffee pod flavors, all on auto-delivery.  Highly recommend.  Yum.

Example Input: Love the cinnamon taste but way too sweet. I gave this to my Mother who loves sweets and she said she couldn't eat it either. Need to promote the cinnamin dlavor and cut the sugar
