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: The first time I tried this product was 2 years ago at the Venetian spa restaurant in Las Vegas having a cup of tea with some friends. We all remarked how delicious and tasty it made our tea. We've been using it ever since. A little goes a long way and I use it anytime I would ordinarily use a sweetener. Since the artificial sweeteners are so unsafe and unhealthy and I have a sweet tooth, I felt this was a safe alternative. Not only is it safer, but there's no aftertaste and doesn't raise your blood sugar level. This particular stevia has absolutely no bitter taste to it. I've tried others before and since and there's no comparison.
Example Output: 5

Example Input: Used to eat the Spicy Thai flavor all the time. MSG makes my body unhappy and this was one of the few flavored chips that was MSG free. Now they have changed the whole recipe and how they make them. Instead of being real food on the ingredients like it used to be its mostly processed chemical garbage, a bunch more salt and MSG stuffed in under the label "yeast extract". They removed the NO MSG from the label so they know very well what they did. The worst part though is that they taste horrible. Instead of crisp, oily and full of character...say as if they were cooked in like...a kettle or something they instead have the color and uniformity of baked lays. The Spicy Thai flavor now tastes like sour cream and onion or ranch that has gone rancid. What a shame, no more kettle chips for me. It seems they are slowly moving one flavor at a time to this new cheap ingredient list and manufacturing method. Dont be fooled into paying a premium price for these chips as they are not a premium product anymore.

Example Input: I really wanted to like these. First off, these cookies are about the size of a half dollar and aren't that thick. And they are more like fudge that cookies. Look at the ingredients. They are nut flour held together with honey. They need some egg or something. They are gooey and sticky. They are extremely sweet and pack a whopping 10-15g carbs each and yes that is not counting the fiber. I'm sorry I appreciate the effort guys but in my option these are a novetly. They are too expensive and too non-functional to be a serious part of your regular diet.
