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 thought I was doing my kid a favor when I invested in a case of Earth's Best dinners.  Unfortunately, the second ingredient (after water) for all of these is....applesauce.  Or in the case of the "Sweet Potato & Chicken" variety, it's sweet potatoes, followed by apricot puree.  After getting used to the sweetness of these (try 'em - they're like jam), it's difficult for kids to adjust to "real" food.  From now on, I'm going to stick with just pureeing home-cooked food.  It's a lot cheaper, too.
Example Output: 3

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 Output: 1

Example Input: All and all it is my fault because I did not pay attention to what I ordered. When I went to the Jack's Links website it advertised white meat 95 to 97 percent fat free. At the time they did not have this product for purchase. So when I received an email saying it was now available I hurried and ordered it. It is not until I received the order did I realize I had ordered dark meat. I did not even know that dark meat was available; therefore, I was shocked and felt deceived. Yet, I had tasted the chicken nuggetts before reading the content and was wondering why was it so salty. I did get a formal apology in writing from jack's links but again it is still my fault for not paying attention. Now I am stuck with many packets of dark meat chicken nuggets. In conclusion, I guess it is still a little bit healthier than the beef. (maybe)
