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: Found these while looking for good, cheap, low-calorie snack packs to buy in bulk for my office.  After my first shipment, I decided to have two boxes shipped to the office monthly via subscribe & save.  My next shipment arrives in two days. I'm so excited!  Gotta have my pop chips...
Example Output: 5

Example Input: OK...but would never buy them again my husband ate some...   I thought they tasted a lot like the chips they used to call MUNCHO'S!   Just not for me!
