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: Neat concept. Other contraptions to use your own coffee have prepunched holes and are designed much differently than the K-Cup. This is like a do it yourself K-Cup. However, because this consists of a disposable cup, filter, and a cap and is punched by the brewer, I would not be surprised if this mechanism infringed on Keurig's patents. Oh, and the video review submitted by the other reviewer looks suspiciously like the video on the manufacturers website :)
Example Output: 3

Example Input: I don't know how people could say this doesn't smell or taste bad. It is horrible!! I was getting raw goat's milk for quite a while and when we moved it wasn't available. The fresh raw milk was delicious and mild and did not have that gamey odor and flavor that this milk has. Maybe some people don't mind the taste, maybe some acquire a taste for it, and maybe some even like it, but I think it is vile. If you like the taste of the goat's milk cheese in stores, then you may like this, if not, stay far, far away!
Example Output: 1

Example Input: I had heard about their prickly pear tea in a forum and decided to try it since I hadn't had any since I was in Arizona. It was better than I remembered! I tried it first hot and then used the remainder for ice tea and both were really good. The company delivered super fast too which was great. I recommend this tea highly, particularly if you like prickly pear teas.
