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: This is a good idea in theory but doesn't work well in practical application.  The things do not all cook property.  About half of them are puffed, some are partially puffed and the rest won't puff no matter how much you cook them.  I follow instructions, measure and have a good microwave.  I usually have to cook twice as long as stated to get any puffing at all.  The flavor is ok but just awful compared to commercial pork rinds purchased in the grocery store.  I also end up with very little that I can eat out of a batch.  They also taste just awful.
Example Output: 1

Example Input: Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it.  I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*
Example Output: 3

Example Input: Both of my cats vomit from all Temptations treats, but especially the Hairball variety. One of my cats actually is getting hairballs from these treats when he didn't before. I've tried all of them, and minutes after they eat their treats they vomit. This doesn't happen with any other treats like Whisker Lickins or Pounce.
Example Output:
