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: These are great beans for the price. If you live in a big city, however, I'd suggest buying green beans at a local Ethiopian shop or even a community Coop. I also remember a Pea berry out of East Timor that was outstanding, but this Tanzanian Pea berry is comparable to standard beans.
Example Output: 4

Example Input: It looks pretty, but the contents are very minute and seem to not be of very high quality. There's a plastic cup for the tea that looks like it came from a dollar store. The basket is nice, though.
Example Output: 3

Example Input: Yeah it's gluten free and whatever, but unless that's a really big issue for you and you're having trouble finding sugary drinks to enjoy on your gluten-free diet, there's no real draw to this drink over say, orange fanta or any number of other carbonated juice type drinks. I thought it was massively overly sweet, and I have something of a sweet tooth. The orange flavor wasn't particularly authentic or delicious, and it left a sour aftertaste. I got a free sample this time, and I cannot see actually paying money to buy this product again. On an environmental note, packaging and shipping these things in tiny little cans makes for more waste, and I don't appreciate that either. Not a fan.
