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: Sooo good, I followed some advice and thought outside of the conventional box. Sliced up some cabbage and onion and sprinkled some Mae Ploy chili sauce on it with some Lime juice too, made a nice salad with a kick! also very good with cilantro and daikon.
Example Output: 5

Example Input: We tried these chips because DR. OZ had recommended them on his show as a healthier potato chip alternative.  My whole family loves them, we have not found a flavor that we don't like.  These are WAY better than any baked style chip.  Try them and you won't be disappointed!
Example Output: 5

Example Input: My reason for the low rating is that there was no "use by" date on the bag, making it difficult to know if the beans were old and not well cared for or if that's just the way Tanzanian peaberry beans roast up.  Not sure how a manufacturer gets away without putting a date on their products, but this supplier has found some way to get around it.  The coffee does taste good, although a hint of staleness exists, but the beans are totally dry: no oil, no moisture is present when they are ground.  I've enjoyed peaberry coffees from Hawaii for years, peaberries are the best of the best beans.  I've also come to enjoy African coffees for their full yet mild taste. So, to find peaberry coffee from Tanzania at such a great price was too much to pass up.  I expect to finish up the coffee I've purchased, but probably wouldn't buy it again or buy any coffee from this supplier since I have no assurance of its freshness.
