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: I had to be taken to the ER in an ambulance earlier, the day before yesterday. I was having seizures, near-syncope (passing out, but still being somewhat conscious), couldn't breathe, and my blood pressure was at stroke level. I felt like and thought I was dying (or maybe already) dead for about 3 hours. It was painful and horrifying. I think I figured out what it was that caused my near-death experience. It was probably the energy-shot I took 20 minutes before then. I don't usually take something like that. Someone offered it to me, and I was so tired, I didn't even look at the bottle and took it. Please, don't use these!

Example Input: If this was called "Medium Roast", I would give it 4 stars. It's a good coffee.  But this is called French Vanilla Caramel, and this review is based on the product's name.  Let me say that vanilla and caramel are perhaps my favorite flavors... coffee, ice cream, candy, you name it... if it's vanilla or caramel, I love it.  With the exception of this.  Where's the vanilla? Where's the caramel? And don't get me wrong: I'm not trying to say that the flavors are too mild. I'm saying that they are NON-EXISTENT. And therefore, based on the name, this coffee gets 1 star.

Example Input: I'm addicted to salty and tangy flavors, so when I opened my first bag of Sea Salt & Vinegar Kettle Brand chips I knew I had a perfect complement to my vegetable trays of cucumber, carrot, celery and cherry tomatoes. Skip the dip; balance the tangy chips by alternating bites of raw vegetable.  As an Oregonian, I'm proud to share these delectable snacks with friends, especially those living outside our state and who haven't experienced gourmet chips. I tell them Kettle Brand does for potato chips what microbrews did for beer.  Kettle Brand potato chips are unmistakable--a light gold color, rich flavor and amazing crunch. Kettle Brand chips are also a healthier snacking option than the major chip brands. Kettle Brand chips don't have trans fats, MSG or artificial flavors and colorings. The company also has a line of organic potato chips and all of their products are certified Kosher.  I also recommend <a href="http://www.amazon.com/gp/product/B000G6MBV4">Kettle Chips Honey Dijon</a> and <a href="http://www.amazon.com/gp/product/B000G6Q4GM">Kettle Chips Spicy Thai</a>.  Annette Solomon, a reporter for the Salem Statesman Journal recently noted that a glass of wine goes nicely with these chips. Solomon wrote, "...you could be missing out on a wonderful pairing. These chips are spicy, so you would want to select a semi-sweet white wine. Also, a moderate amount of acid will subdue the strong flavors of ginger, lime, garlic and cilantro without over-powering them. Classically, a German-style Riesling fits these parameters perfectly."
