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. 

Ex Input:
These are way better than rancid grocery story peanuts, but they weren't as good or as fresh as I'd hoped. I imagine that they'd been stored too long at amazon before being shipped.  Too bad, because if they're not going to be absolutely fresh, why would I buy these again?

Ex Output:
3


Ex Input:
I have this on auto ship because I use it so much. I have gone to every grocery in AZ and the cheapest place is Amazon! This is a great product and whatever you make using this flour will taste great. My son has Celiac and is allergic to gluten. I have tried every pancake mix and this one is the one I settled for!

Ex Output:

Ex Input:
So many "healthy" products don't taste very good.  Or taste good when you first try them and then go downhill.  I've had these chips on more than one occasion and they are very tasty.  I've served them to guests twice and both times they wanted to know what they were and where to get them. It's also nice to have something gluten-free for friends who are borderline diabetic...but I would eat them anyway.
