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: You know, I was searching the Internet for the words "temptations" and "vomit" when I came across these reviews. I was surprised to hear that I'm not the only one who has had problems with this product. Within an hour of eating these treats my cat vomits for about 40 minutes. I didn't realize it was the cause until the second time I fed them to her. It's really bad because it doesn't cause the cat to throw up all at once. It's like she can just vomit a little at a time and you're forced to follow her around cleaning up all the vomit ((or locking her in the bathroom (which is horrible)).
Example Output: 1

Example Input: I love this candy. After weight watchers I had to cut back but still have a craving for it.

Example Input: I usually enjoy a cup of coffee a few days a week, more as an indulgence than as a necessity. It's a sipping beverage for me, and flavor matters a lot. That said, I add milk and sugar, so I'm not excessively picky (or I think so, at least). So I'm always glad to find new "gourmet" blends to add to my list of favorites. This blend seemed promising, with a very nice aroma and a perfect, even grind. I usually grind my own beans, but found that this grind worked nicely in my espresso machine as-is. It even produced a rich, smooth crema. Unfortunately, my first sip - without sugar or milk - was very bitter. I ended up adding about a half-teaspoon more sugar than I usually use just to compensate. Even then, the coffee flavor, itself, was thin and weak. With just a little milk added, it tasted more like, well, flavored milk. This coffee reminded me of the inoffensive bland coffee my parents used to get for our drip coffee maker a couple of decades ago. Fine for that application, but not really what I'm looking for in rich, smooth flavor with low bitterness.
