Shocked, but not necessarily awed.
Surprisingly, Diet Mountain Dew Code Red (with a rush of cherry flavor) isn't entirely horrible.

I don't like it. But since it's the only available caffeinated drink in the building at the moment, I will drink enough of it so that I can justify throwing the rest of it away without saving it for a later time when I may be in need of a caffeinated beverage.

Wait, I just discovered that the 'best by' date on it is Oct 27, 2003. Is that bad?

Code Red! Code Red! Mayday! Mayday!
