Example Input: This stuff sounded perfect...way too much red dye and no taste according to me and my 3 friends who tried it...kind of salty.  Basically, I would stay away from it.  I am tempted to toss it out, but paid too much to feel right about it...
Example Output: 2

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.
Example Output: 1

Example Input: I am so surprised that they have this popcorn for sale.  I received 6 bags the other day and the special popcorn pan from Wabash Valley Farms Amish Country ....GOURMET ... well.. the popped kernels are the size of a pea and with hulls.  It burns very easily.  There are too many old maids due to the delicate nature of the kernel.  I ended up throwing most of the popped corn away.  I am so disappointed in this product.  I now have 5.75 bags of this stuff ... I have nothing good to say about it ... but if you like tiny popped corn with lots of hulls then this may be your product.  I am giving mine to the squirrels.
