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: We wanted the Baconnaise lite after seeing the product on Oprah. We looked forward eagerly to the  prospect of that great bacon taste. The decision in our house was 1 for and 1 not so. The taste is there, the "greasy" taste was also. I won't buy the product again.

Example Input: I ordered this plant for my seven year old daughter.  She was extremely excited to get it so I even ordered the express 1 day shipping, which I paid over ten dollars for, and it still took over a week to reach my house.  Once it got to my house, I opened the box expecting it to be a fully established plant, which would look similar to the picture shown.  This is not the case.  It came as a pot, a bag of soil, and a damp paper towel with a VERY small plant inside...maybe 1 inch long.  There were absolutely no care or planting instructions or anything like that at all.  We were pretty disappointed.  However, I was able to plant what was there in the dirt and it seems to have survived and looks a bit better now.  My daughter is happy with this plant now, but it was a rough start.

Example Input: I wanted to give these soy crisps more justice than just the 5 stars (and ordering them all the time).  I bought a bag of these Sea Salt flavor crisps and a bag of BBQ crisps about a month ago, in a bid to eat more healthy food.  I've always loved BBQ chips, especially Ruffles and Lays K.C. Masterpiece chips, but they've got to be killing me slowly, right?  So I busted open the BBQ soy crisps and gagged.  How could this be BBQ?  They tasted like cardboard, and I gave them to my friends who will eat anything.  I begrudgingly opened the Sea Salt bag, and though more palatable, I was still disappointed.  (I know..."I thought you said 5 stars."  It gets better.)  Anyway, I had sworn off chips and midday snacking, so for two weeks I saw nothing on the counter but Genisoy Soy Crisps.  I'd eat two or three here and there, and when I ran out, I bought 2 bags of the Sea Salt flavor again.  What happened must be akin to rebooting your computer or defragging your hard drive--my body forgot what those strong BBQ flavored chips were like, and I started craving Soy Crisps.  I began to taste a delicious roasted soybean flavor, like those roasted and salted soy beans they sell in jars, which I had completely missed before, apparently because it wasn't a sweet, red-crusted, overbearing BBQ powder.  I polished the next bags off in three days.  Now, I'm ordering 12 here on Amazon ($1 cheaper per bag than my local grocery store which seems to want to punish my wallet for trying to eat healthy food).  My advice is this--give these soy crisps a chance, but don't mix them in with your regular Doritos and BBQ Ruffles or you'll think they're awful.  Stop eating, for a month, the oily BBQ chips that have deadened your taste buds for years and reboot your taste buds with these markedly healthier chips.  You'll feel better about snacking!
