Cool Mountain Fountain Classics Razzberry

This is a bright blue soda that looks eerily like the poison that Christian Slater mixes up to feed to the girl in Heathers. You know the one that makes her fall right over into the glass table.
It tastes like you might expect, like a melted freezie pop. Unfortunately it has a pretty bad aftertaste. It tastes almost diet. How does something with cane sugar have a diet aftertaste?
The cap asks the question "Are you thirsty?" I have to answer "Yes, yes I am because your beverage wasn't very good and I didn't finish the whole thing and pawned it off on my friends."
