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: It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.
Example Output: 4

Example Input: I've tried all three new 'Dark' offerings from Gevalia and I think this is the best one from the three. Gevalia finally came up with coffee worth serving to your guests. Coffee has an earthy bold taste with little to none bitterness and no metallic after taste; it actually leaves a nice smooth tasty chocolaty after taste.  The pack comes with 12 big T-discs that will brew 8 ounces of coffee. This coffee will delight those who love the darker roasts.  Update: I am on my 5th cup of this coffee and it was really grown on me (changing from a 4 to 5 stars); it is quite tasty and smooth. This is one coffee that will truly satisfy the void that Sbux left. There will be some that will say that this is not the same as Sbux and it isn't! Try the coffee and give it a fair taste without trying to compare it to anything else you may find yourself quite surprised at the findings.  Highly recommended and definitely will be buying this one again.
Example Output: 5

Example Input: I had a handful of these crackers last night - and though they are tasty, my hands, face, and ankles swelled to a ridiculous size.  I wasn't sure if it was the crackers or something else I ate - so I ate them by themselves at lunch - and again, I am a swollen mess.  I didn't realize the MSG content was so high.  I won't be eating these again.  If you react to salt, sodium, or MSG - just stay away from these tasty little buggers.
