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 a recurring shipment of this product each month.  Every month when the boxes arrive they are barely in one piece and VERY mangled.  Last month one of the cases of water had to be repackaged before it arrived and it was a day late.  I suggest using a more sturdy box for shipping.  The water product is fine ... it's just the shipping packaging I have a problem with.
Example Output: 2

Example Input: I bought a new bread machine and bought this collection of bread mixes as well as some single mixes to try it out.  The single mixes worked well as they included yeast packaged separately in the mix.  My machine states clearly not to get the yeast wet, to put it on top of the flour away from the water.  The mixes in this collection have the yeast in the flour, not packaged separately.  The bread failed to rise at all.  Why would they package the yeast separately in the single mixes and not in the multi packs?  Along with the Heartland Collection I also purchased the Baker's Choice Collection.  I am throwing them all out.  Don't waste your money.
Example Output: 1

Example Input: I ordered this because so many people were saying that it was sugar free. It's not. The first ingredient is "SUGAR". It's too much of a pain to return, so I'll keep it and drink it (because it's a pretty good K-cup hot chocolate). I will think twice about ordering it again though. I'd really like to get what I ordered.
