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 just received these bricks today and was very disappointed to find that BOTH of the bricks were broken and unusable as a serving/cooking plate.  They were busted completed in half. They were packaged in one sleeve of small bubble wrap in a shallow box with no other protection or packaging in the box.  I went online to try and return them and they are not eligible for return.  This is the first return I've ever tried to do in over 7 years of purchasing items off of amazon (to the tune of several orders a month!) and yet the one time that I want to return a defective product, I can't do it.  I will be much more careful about what is eligible for returns and what isn't in the future.
Example Output: 1

Example Input: OK,I did read the reviews which ranged from splendid to awful. I took the plunge as I do like salty, and tangy flavors. No, I had never had these before I took the leap and ordered a case at a super price. They arrived quickly and in great shape with the sell by date  FEB 2011. Umm, I'm in the middle on these chips, they are OK but not something I can't live without. I love the crunch, the color, NO TRANS FAT. They are a little too vinegary for my taste, which is a lot coming from a kid that grew up eating pickled hard-boiled eggs and pickled pigs feet.  I haven't tried them with a deli sandwich and a cold mug of beer which might improve the experience :)
Example Output: 3

Example Input: I didn't mind the taste of this very much - it tasted like Minute Maid OJ mixed with soda.  My husband couldn't stand it at all.  My only issue with this was that it was a heavy-syrup sort of flavor that was a little overwhelming.  If there was a better balance of flavor to liquid to make it a little lighter tasting, I think this would be much more refreshing and enjoyable.  Might be fine for kids though - since they like that sugary orange stuff.
