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 bought two bags of these, thinking it was the same product that I used to buy in different packaging (light blue, with a see-through dog shape against a grass green background). Unfortunately, it was completely not the same thing! These treats were actually like jerky-- tough and brittle. I give my dog soft treats because he doesn't chew the damn things, and he choked on these horrible things; I had to toss them out.  Note that the "Zuke's Jerky Naturals" with the other packaging (http://www.amazon.com/Zukes-Jerky-Naturals-Beef/dp/B00008DFPY) have always been moist and soft, and I've never had a problem with those. I suspect that this batch was not new packaging, as I had thought, but very old packaging; these may be the same treats I usually feed my dog, just having sat on a shelf for years. In any case, these were COMPLETELY different treats, and not safe to feed my dog.
Example Output: 1

Example Input: The only reason for the 3 stars was the packets the individual teas were in.  I love this tea, I have the ones in the tin on auto delivery.  I was taking a trip, and ordered these so I could take some with me on my trip.  Prior to leaving home I took some out of the box and put them in my suitcase.  I got to the hotel and tried to open the little packages.  Impossible to open the individual packages.  No knife with me, I ended up using a toe nail clipper to open the individual packages of each tea.  Hopefully this was just a problem with the first box, but I would not recommend buying this tea in the boxes, go for the cannisters.  If you do buy the boxes have something near by to open each and every packet of tea.
Example Output: 3

Example Input: I bought these because of the good reviews and I now think the reviews came from employees or some such thing.  They are not the color of chestnuts, plus they are wet in the package and the taste and texture is way off.  I had to order 24 packs of them and they are not-returnable and yet I cannot even finish the first pack.  I would really suggest either get your chestnuts fresh and roast them yourselves or do without because if you are like me who has been roasting and enjoying for 50+ years you will be terribly disappointed.
