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 dieting, and I use these as a "treat" to myself, when I'm craving chocolate.  I usually brew one of these & one of my coffee K-cups (either plain or hazelnut).  For 60 calories, it's not a bad way to satisfy a chocolate craving when you're on a "calorie-budget!"
Example Output: 3

Example Input: I love this product! It is the best natural sweetener I have ever tried, and I have tried many. You can use also as pancake syrup or as a substitute for honey on your peanut butter and honey sandwich. It last a long time, and is a good value.
Example Output: 5

Example Input: First, let me state that I brew most of my tea in a gaiwan, hence, I use loose leaf tea.  White tea is one of my favorites so I'm always on the lookout for a nicely priced Bai Mudan.  As much as I love Bai Hao Yinzhen, I just cannot afford to drink it exclusively due to the volume of white tea I drink.  I thought this was a pretty good price and when I opened it up it didn't look too bad either.  Much to my surprise, after taking the first layer off the top (I transfer my tea to good tea tins) it was nearly all powder/dust with hardly any intact leaves.  This is extremely problematic if you don't use any filters or screens (like me).  I don't mind when some tea leaves get in my tea and it is pretty much normal if you don't pour through a screen, however, this was so broken up that it was just unworkable.  I have only opened one bag at this point so there is a chance that it was just that bag or possibly even a bad batch but at this point I most likely won't be ordering it again.  That being said, the whole leaves that were there (on the top) looked fine.  It does have a bit of a green tea taste (vs some other high quality white tea I am used to), however, it isn't bad or anything.  Definitely drinkable on a regular basis if the bag wasn't mostly powder.  I took a couple pics so I will post them...keep in mind this came in two pouches, I poured into tins and that is where I took the pictures (the product does not actually come in tins).
