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: Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level. Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.

Example Input: My son had this Jablum roasted and ground coffee brought back from Jamaica and paid a lot for it. I have drunk blue mountain for years when I can but this was shocking. It tasted stale when you opened the bag and even worse when you drank it. It was definitely off. He bought 5 bags and every one we tried was the same. I would never buy another. We had bought another brand in a tin from Jamaica which was fine. I think this is a con. You get all the rubbish about it being tested in Jamaica, well I dont know who tests it but definitely not someone who likes good coffee. I just dont understand how people say its any good. Maybe having paid so much for it its like the emperor's new clothes.

Example Input: I bought a case of this stuff (Dark Chocolate) based on the positive reviews. Big mistake. This is half a step above Swiss Miss. It is definitely not up to the level of Archer (Target brand), Twinings (some grocery stores), or Cadbury (overseas or very few grocery stores). Cocoa is the 4th ingredient. No chocolate as an ingredient. Bunch of fats and fillers. Archer has cocoa as the second ingredient and chocolate as the 4th and 5th ingredient. That's more like it. Stephen's chocolate has bad/very light color, little aroma, thin, doesn't dissolve. A very disappointing purchase.
