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'd been hearing about the product for a couple of years and finally ordered some, but inadvertantly ordered lite! Yuk! After much anticipation, waiting for it's arrival, and then finally opening up the (cheap plastic) jar and putting some on a piece of bread to try it with.... it tasted like wall spackle. Ok, I've never eaten wall spackle, but I'm pretty sure it tastes like "lite" baconnaise. Then I realized after careful examination of the label that I ordered the "lite." Dammit.  Determined to finally taste the ORIGINAL baconnaise, I went back on amazon and (very carefully) ordered the ORIGINAL baconnaise. And it's pretty dang good! I'll leave a review of the original, non-lite product there.

Example Input: Tastes like pine needles!!! I've had other earl greys before and never have I thought I was drinking pine needle tea (Another reviewer said it was a bergomot flavor, i'm not educated enough to know)...  I bought this for my wife who can't have caffeinated varieties, and I can say i'm not a big fan.  The English Breakfast decaf is EXCELLENT.  I prefer my tea black, hot or cold, but this earl grey is not tolerable unless drank with a splash of milk and sugar (splenda for me though). It is undrinkable as iced tea.  I'd return this if i could. Avoid this at all costs, young jedi.
