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: With <a href="http://www.amazon.com/gp/product/B00389Q4XW">Green Mountain Hot Cocoa</a> being perpetually out of stock in the winter, I thought I'd give the cheaper Grove Square brand a shot.  Since the K-Cup patents are starting to sunset, Grove Square is one of the first "unofficial" producers of "we can't legally call these K-Cups but they work in your Keurig(R)(TM) coffee maker" pods, and I thought that I'd be getting the same overall quality, without the licensing fees tacked on to the price.  Well... I was right about Grove Square being cheaper. But I think that's the nicest I can be.  As others have pointed out, there's a definite "diet" or "<a href="http://www.amazon.com/gp/product/B000E6LBXK">Splenda</a>" aftertaste. This hadn't been reviewed yet when I bought it, so I didn't see the warnings from others, and re-checked the ingredients several times to make sure.  "Well... it's got 60 calories, which seems a bit lower than Green Mountain, but a bit high for something that diet-conscious people would want." and the ingredient list didn't seem to point to obvious "diet" sweeteners.  The overall taste is kind of like someone dropped a sugar-free Tootsie Roll in your hot water, using the normal cup setting. Going one size down didn't seem to improve much, beyond making a weak chocolate flavor sweeter - but that just meant a heavier shot of low-calorie sweetener to the taste buds.  The way I see it, I saved about $5 by going with this brand. On the other hand, now I've got 20 of these cups left that are probably going in the trash if I can't sucker someone... er... please my discerning guests... with a few cups.  If you drink diet soft drinks by choice, you're probably going to like this.

Example Input: Not one member of my family, including me, like these extremely salty, much too strong a BQ taste to order more.  I purchased them on a recuring basis and i wish to cancel now.  I have received only one shipment. Cancel further shipments.  Not to our taste at all. These are Lowery pork rinds.

Example Input: This tea was horrible.  It tasted like potpourri.  I have really enjoyed other Davidson's teas,many also containing flowers, and thought to try something new.  I think the last ingredient is where things went bad.  It was "natural flavor"  which must have been rose oil or something since my tea chemical taste and making a weaker tea did not help at all.
