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 never taken the time to write a review before, but in this case others need to be warned off. I expected to get a product similar to what I have seen in the stores, but this obviously is a replica. The sliders on the bottom of the tray that are supposed to keep the tray straight when you slide it in and out broke off before I even got it out of the package. It is not something you can fix unless you have a solder gun. Even then, it is very "sticky" pulling the tray out because there are no rollers. It is metal on metal, which does not work well without some sort of lubrication. I love Amazon, but this product is inferior at best.

Example Input: I am a huge fan of Genisoy Soy Crisps (Deep Sea Salted flavor). I love the crunch and texture of this non-greasy snack.  The flavor is subtle and very light.  No heavy salty taste or greasy lips or fingers after eating.  I also like that I can really indulge on these and not feel the regret of eating too many calories.  Soy Crisps are my fav crunchy treat.  >^,,^&lt;
